The formula for dimethyl mercury is. HgC2H6 = (2x12) + (6x1) + (1x200.6) = 230.6
So the molar mass of dimethyl mercury is 230.6 g/mol.
Number of moles in 4.2g of dimethymercury = 4.2/ 230.6 = 0.0182 moles.
1 moles of dimethymercury contains 6.02 * 10^23
Hence 0.0182 moles contains X
X = 0.0182 * 6.02 * 10^23 = 0.10952 * 10^23 = 1.0952 * 10^22.
Okay so molar mass is given, no. of moles is given and we have to calculate the weight or mass of the compound in gram.
the formula we will use here is= n=W/M
where n is no. of moles ,w is weight in gram which we have to find and M is molar mass or formula weight which is given.
so W=n x M
use this formula you'll get the answer
It’s the 3d one
Good luckkkkkkkk
