Answer:
168 L
Explanation:
Given data:
Mass of hydrogen gas = 15 g
Volume occupied = ?
Solution:
First of all we will calculate the number of moles of hydrogen gas.
Number of moles = mass/ molar mass
Number of moles = 15 g/ 2 g/mol
Number of moles = 7.5 mol
One mole of any gas at STP occupy 22.4 L volume.
The standard temperature and pressure is 0°C and 1 atm.
Thus the volume occupy by the 7.5 moles hydrogen gas is,
7.5 mol × 22.4 L/1 mol = 168 L
Answer:1
Explanation: There is only one orbital in the s sublevel. It can hold up to two electrons.
Answer:
decreases
