Question

How many grams are in 3.00 x 10^24 molecules of Zn(C2H3O2)2?​

Answer 1

Mass = 917.4 g

Step-by-step explanation:

Given data:

Number of molecules = 3.00 ×10²⁴ molecules

Mass in gram = ?

Solution:

1 mole contain 6.022 × 10²³ molecules

3.00 ×10²⁴ molecules × 1 mol / 6.022 × 10²³ molecules

0.5×10¹ mol

5 mol

Mass in gram:

Mass = number of moles × molar mass

Mass = 5 mol × 183.48 g/mol

Mass = 917.4 g
