calculate the number of moles,molecules,and neutrons in 49gm of h2so4
Number of moles = Given mass / molar mass
= 49 g/ 98 g mol-1
= 0.5 mol
Number of molecules = Number of moles x 6.022 x 1023
= 0.5 x 6.022 x 1023
= 3.01 x 1023
Number of moles of protons in 98 g H2SO4 = (2 + 16 + 4 x 8)
= 50 mol
Number of moles of protons in 49 g H2SO4 = 50/2 = 25 mol
Number of moles of Neutrons in 98 g H2SO4 = Mass Number - Number of protons
= 98 - 50 mol
= 48 mol
Number of moles of Neutrons in 49 g H2SO4 = 48/2 = 24 mol
= 24 x 6.022 x 1023
= 1.44 x 6.022 x 1025
= 49 g/ 98 g mol-1
= 0.5 mol
Number of molecules = Number of moles x 6.022 x 1023
= 0.5 x 6.022 x 1023
= 3.01 x 1023
Number of moles of protons in 98 g H2SO4 = (2 + 16 + 4 x 8)
= 50 mol
Number of moles of protons in 49 g H2SO4 = 50/2 = 25 mol
Number of moles of Neutrons in 98 g H2SO4 = Mass Number - Number of protons
= 98 - 50 mol
= 48 mol
Number of moles of Neutrons in 49 g H2SO4 = 48/2 = 24 mol
= 24 x 6.022 x 1023
= 1.44 x 6.022 x 1025
