- 60.6 g

Solution:- The balanced equation for the given reaction is:

$2Na_3PO_4(aq)+3Ca(NO_3)_2(aq)\rightarrow 6NaNO_3(aq)+Ca_3(PO_4)_2(s)$

It is a grams to grams conversion problem. Here, first of all the given grams of calcium nitrate are converted to moles on diving by its molar mass. Then it is multiplied by the mol ratio to get the moles of calcium phosphate and finally multiplied by molar mass of calcium phosphate to get its grams.

From balanced equation, there is 3:1 mol ratio between calcium nitrate and calcium phosphate.

Molar mass of calcium nitrate is 164.088 g per mol and the molar mass of calcium phosphate is 310.18 g per mol.

$96.1gCa(NO_3)_2(\frac{1molCa(NO_3)_2}{164.088gCa(NO_3)_2})(\frac{1molCa_3(PO_4)_2}{3molCa(NO_3)_2})(\frac{310.18gCa_3(PO_4)_2}{1molCa_3(PO_4)_2})$

= 60.6gCa_3(PO_4)_2

So, the mass of calcium phosphate the reaction can produce is 60.6 g.

Answer from: alexis3060

Answer is: The mass of calcium phosphate the reaction can produce is 60.8 grams.

Balanced chemical reaction:

3Ca(NO₃)₂(aq) + 2Na₃PO₄(aq) → 6NaNO₃(aq) + Ca₃(PO₄)₂(s).

m(Ca(NO₃)₂) = 96.1 g; mass of calcium nitrate.

n(Ca(NO₃)₂) = m(Ca(NO₃)₂) ÷ M(Ca(NO₃)₂).

n(Ca(NO₃)₂) = 96.1 g ÷ 164.1 g/mol.

n(Ca(NO₃)₂) = 0.58 mol; amount of calcium nitrate.

From chemical reaction: n(Ca(NO₃)₂) : nCa₃(PO₄)₂ = 3 : 1.

n(Ca₃(PO₄)₂) = 0.58 mol ÷ 3.

n(Ca₃(PO₄)₂) = 0.196 mol; amount of calcium phosphate.

m(Ca₃(PO₄)₂) = n(Ca₃(PO₄)₂) · M(Ca₃(PO₄)₂).

m(Ca₃(PO₄)₂) = 0.196 mol · 310.18 g/mol.

m(Ca₃(PO₄)₂) = 60.8 g; mass of calcium phosphate.

For cyclohexane compounds drawn in a chair conformation: -axial bonds are vertical -equatorial bonds are parallel to two bonds within the ring. thus, as i assume the chair conformation is drawn: -the x group is in an axial position, as are the five other vertical bonds. -three axial bonds are on the top face of the ring -the other three axial bonds are on the bottom face the position of the second substituent on each ring carbon is equatorial. gauche groups must be on an adjacent carbon such as carbon 6 and carbon 2, and also gauche groups are rotated by 60 degrees relative to each other. drawing the newman projections for c1–c2 and c1–c6 aids in visualizing the groups that are gauche to the y group on c1. click this link and watch some academic videos that may you more understand the topic

Since the gas in your graduated cylinder is a mixture of butane and water vapor, you must determine the partial pressure of the butane, pbutane, alone. to do this, consult a reference and record the partial pressure of the water vapor, pwater, at the temperature you recorded. use the following formula to compute the partial pressure of the butane. pbutane = atmosphere - pwater use the following combined gas law formula and compute the volume that the butane sample will occupy at stp. (hint: convert both temperatures to kelvin.) pbutane x voriginal = pstandard x vfinal troom tstandard use the following ratio and proportion formula to determine the mass of butane needed to occupy a volume of 22.4 l at stp. grams of butane you used “x” grams of butane ml of butane corrected to stp = 22,400 ml compute the theoretical molar mass of butane based on its formula and the atomic masses on the periodic table. compare your experimental results from #3 to the theoretical value of #4, computing a percent error of your findings using this formula: % error = measured value - accepted value x 100 accepted value use the following ratio and proportion formula to determine the mass of butane needed to occupy a volume of 22.4 l at stp. need asap
