6.23L volume of h2 gas is produced at stp.
Given that one mole of dihydrogen (H2) weighs 2,0159 g/mol, the experimental density of hydrogen—which is 0,0899 g/L at 0 °C and 0,0837 g/L at 20 °C—can be used to compute the exact molar volume of hydrogen.
This implies that at STP, one mole of hydrogen also takes up 22.4 liters of space. Therefore, at STP, 10moles of hydrogen gas will take up =22.410=224litres of space. In other words, when 460g of salt combines with extra water at STP, 224litres (or 224000mL) of hydrogen gas are released.
