Question

How many grams would be in 1.752 x10^26 formula units of Ca(No3)2

Answer 1

47730 grams.

Step-by-step explanation:

First we convert 1.752x10²⁶ formula units of Ca(NO₃)₂ into moles, using Avogadro's number:

• 1.752x10²⁶ formula units ÷ 6.023x10²³ formula units/mol = 290.88 mol

Then we convert 290.88 moles of Ca(NO₃)₂ into grams, using the molar mass of Ca(NO₃)₂:

• 290.88 mol * 164.088 g/mol = 47730 g
