There are 3 significant figures in 0.0000246 g.
The product of 0.12 g, 1.8 g, and 0.562 g should have the same number of significant figures as the measurement with the fewest significant figures, which is 0.12 g in this case. Therefore, the product should be expressed with two significant figures.
it would be 0.03 just round up, two significant figures means two figures after the decimal point. If it was 3 significant figures then it would be 0.04 etc....
The molar mass of water is approximately 18.02 g/mol. Therefore, one mole of water would weigh approximately 18.02 grams, considering 4 significant figures.
To find the number of moles in 1.18 g of NO2, you need to divide the given mass by the molar mass of NO2. The molar mass of NO2 is approximately 46 g/mol. So, 1.18 g / 46 g/mol = roughly 0.026 moles of NO2.
