0.00340500 would be counted as 6 significant figures. The way you count is (from the left) the first non-zero digit would be the 1st significant digit. However, any zeros that appear behind that first significant digit is still counted not skipped. The value, rounded off to one significant figure, is 0.003. Do note that even if the number is exact, you have to add the extra zeros behind. For example, state 5 in 3 significant figures would mean the answer would be 5.00 The difference between 5 and 5.00 is that the two extra zeros indicate a level of precision that is 100 times greater. These zeros are not merely place holders.
The least number of significant figures in any number of the problem determines the number of significant figures in the answer which, in this case, would be 932.
75.6 times 12.33 = 932.148 correct to 6 significant figures

You can lift a 20 kg weight over your head ten times before getting tired (20 kg, 10 times). This answer is accurate to two significant figures.
There will be three significant figures in the answer to 223.4 times 7.5, which is 1675.5. The least number of significant figures in the original numbers (223.4 and 7.5) is 3, so the answer should also have 3 significant figures.
12.6 * 0.53 = 6.68 in significiant figures
