29.26 gram
Explanation:
No of molecules = no of mole × Avogadro's number
No of molecules = mass in gram/ molar mass × Avogadros number
Mass in gram =No of molecules×molar mass / Avogadros number
Mass in gram = 3.012 ×10^23 × 58.5/6.02×10^23
29.26 gram
9.04354 * 10^2
The “*” identifies as a multiplication sign. Hope this helps

Answer:
4725.6 g of (NH4)2SO4
Explanation:
Molar mass of a substance is the number of mass of the substance contained in one mole of the substance. It is also called the formula weight of the compound. The formula mass of (NH4)2SO4 is 132 g/mol Hence;
Now we know that;
1 mole of (NH4)2SO4 contains 132 g of (NH4)2SO4
35.8 moles of (NH4)2SO4 contains 35.8 * 132/1
= 4725.6 g of (NH4)2SO4
