What is the mass, in grams, of 1.50 mol of iron (iii) sulfate? express your answer using three significant figures. mm = nothing g request answer part b how many moles of ammonium ions are in 6.935 g of ammonium carbonate? express your answer using four significant figures. nn = nothing mol request answer part c what is the mass, in grams, of 1.20×1021 molecules of aspirin, c9h8o4? express your answer using three significant figures. mm = nothing g request answer part d what is the molar mass of diazepam (valium®) if 0.05570 mol weighs 15.86 g? express your answer using four significant figures. mm = nothing g/mol

For A: The mass of iron (III) sulfate is 600. g

For B: The moles of ammonium carbonate is 0.07216 moles

For C: The mass of given number of molecules of aspirin is 0.359 grams.

For D: The molar mass of diazepam is 284.7 g/mol

Explanation:

To calculate the number of moles, we use the equation:

     .....(1)

We are given:

Number of moles of iron (III) sulfate = 1.50 mol

Molar mass of iron (III) sulfate = 399.9 g/mol

Putting values in equation 1, we get:

Hence, the mass of iron (III) sulfate is 600. g

We are given:

Mass of ammonium carbonate = 6.935 g

Molar mass of ammonium carbonate = 96.1 g/mol

Putting values in equation 1, we get:

Hence, the moles of ammonium carbonate is 0.07216 moles

We are given:

Number of aspirin molecules =

Mass of 1 mole of aspirin = 180.16 g/mol

According to mole concept:

number of molecules occupies 1 mole

So, number of molecules of aspirin has a mass of 180.16 grams

Thus, number of molecules of aspirin will have a mass of

Hence, the mass of given number of molecules of aspirin is 0.359 grams.

We are given:

Moles of diazepam = 0.05570 mol

Given mass of diazepam = 15.86 g

Putting values in equation 1, we get:

Hence, the molar mass of diazepam is 284.7 g/mol

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.

the correct answer would be b. amelia, because the particals of gas move really fast (charged particals) and gas also has a lot of room (particals move independently) so the only answer that has both of those is amelia's.
