Question

What is the mass of 5 Moles H2O?



90 g

80 g

110 g

70 g​

Answer 1

Answer:

90 gram

Step-by-step explanation:

From this you can see that 5 moles of hydrogen gas would react with 2.5 of the available 3 moles of oxygen gas, to form 5 moles of water. The molar mass of water is 18 g/mol, so you would end up with 5 x 18 = 90 g of water.
