Calculate the mass of the following
0.5 mole of `N_2` gas

Calculate the mass of the following 0.5 mole of N atoms

Calculate the mass of the following 6.022 times 10^23 number of N_2 molecules

Calculate the number of moles of the following . 52 g of He(finding mole form mass).

Calculate the mass of one mole of electrons?

Calculate the number of particles in each of the following . 0.1 mole of hydrogen

Calculate the molarity of each of the following solution : (a) 30g of CO(NH_(3))_(2).6H_(2)O in 4.3 L of solution. (b) 30 mL of 0.5" MH"_(2)"SO"_(4) diluted to 500 mL. (a) Molarity =("moles of solute")/("Volume of solution litre") and moles of solute =("mass of solute")/("molar solution of solute") So, first find molar mass by adding atomic masses of different elements, then find moles of solute and then molarity. (b) Use molarity equation for dilution. M_(1)V_(1)=M_(2)V_(2) (Before dilution) (After dilution)

The pressure in a monoatomic gas increases linearly from 4 xx 10^5 Nm^(-2) to 8 xx 10^5 Nm^(-2) when its volume increases from 0.2 m^3 to 0.5 m^3 . Calculate the following: molar heat capacity of the gas.
