4 0

For numbers less than 0.1 such as 0.06, the zeros to the right of the decimal point but before the first nonzero digit show the decimal place of the first digit.

The number of significant figures in a measurement often show the degree of accuracy of the measurement. We ascertain the number of significant figures from the first non - zero digit in the figure.

Given the figure 0.06, there is only one significant figure present. The zeros to the right of the decimal point but before the first nonzero digit show the decimal place of the first digit.

How many molecules are contained in a 7.20-g sample of dimethylmercury?
jekas [21]
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.
