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

Mass = 917.4 g

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

? you expect us to answer this? ? this is your schoolwork, i don't think we can with this, i think it would considering being

we need the questions , i may then you.
