Question

calculate how much volume of 8g.hydrogen gas occupies at STP​

Answer 1

Answer:

1mol of a gas at STP occupies 22.4L

1mol of a gas at STP occupies 22.4LIn this case, we have 8g of hydrogen at STP, which is 8g/2g/mol = 4mol

1mol of a gas at STP occupies 22.4LIn this case, we have 8g of hydrogen at STP, which is 8g/2g/mol = 4molSo, at STP, 4mol of hydrogen occupies 4x22.4 = 89.6L
