No your question is not correctly phrased. Anyways, The nucleus of helium atom has mass of 0.05x10^-27kg.
1.23X10^24 helium atoms has mass of 1.23X10^24 multiplied by 0.05x10^-27
= 0.05x10^-27 x 1.23X10^24
= 6.15x10^-5
Now this is the mass of nucleus.
Each helium atom has 2 electrons.
1.23X10^24 helium atoms will have
2.46x10 ^24 electrons.
Multiply number of electrons with mass of each electron and add to 6.15x10^-5 to get the total mass.
1.23X10^24 helium atoms has mass of 1.23X10^24 multiplied by 0.05x10^-27
= 0.05x10^-27 x 1.23X10^24
= 6.15x10^-5
Now this is the mass of nucleus.
Each helium atom has 2 electrons.
1.23X10^24 helium atoms will have
2.46x10 ^24 electrons.
Multiply number of electrons with mass of each electron and add to 6.15x10^-5 to get the total mass.
