A chemist adds of a aluminum chloride solution to a flask. Calculate the mass in grams of aluminum chloride the chemist has added to the flask. Be sure your answer has the correct number of significant digits.

The given question is incomplete. The complete question is:

A chemist adds 95.0 ml of a 1.5M aluminum chloride solution to a flask. Calculate the mass in grams of aluminum chloride the chemist has added to the flask. Be sure your answer has the correct number of significant digits.

 19.0 grams

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.

where,

n = moles of solute

= volume of solution in ml

moles of =

Now put all the given values in the formula of molarity, we get

Therefore, the mass in grams of aluminum chloride the chemist has added to the flask is 19.0

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
