100 points! Chemistry! Please help if you can with the following two questions

Answer 1

H_2S+O_2--->SO_2+H_2O

Balance it

• 2H_2S+3O_2--->2SO_2+2H_2O

So

Molar mass of oxygen=2(16)=32g/mol

Molar mass of SO_2=2(16)+32=32+32=64g/mol

Moles of oxygen:-

• Given mass/Molar mass
• 44.7/32
• 1.399mol

Here

• 3 mol of Oxygen produces 2 mol SO_2
• 1 mol of oxygen produces 2/3=0.6mol SO_2

Moles of so_2

• 0.6(1.399)=0.84mol

Mass of water

• 0.84(64)
• 53.8g
