To three significant figures, the measurement 1246 g should be reported as [number] g.

Chemistry
1 answer:
katrin2010 [14]3 years ago
4 0

Answer:

  • <u>1250 g</u>

Explanation:

The measurement <em>1246g</em> shows four figures. To show this measurement to <em>three signficant figures</em> you must change the last digit to 0 and round properly.

To report the measurement 1246g to three significant figures you must replace the last digit (the 6) with 0 and round the previous one (the 4) to the closest integer: 1250 is closest to 1246 than 1240, so the correct rounding is 1250.

In an integer number, the zeros after the last none zero digit are not sginificant figures; that is why the zero in 1250 g is not significant and this number has just three significant figures.

Which of these statement(s) is/are true about a balloon filled with 1.00 mol N2 (g) at STP?
lara [203]

Answer:

I. The balloon has a volume of 22.4L

III. The balloon contains 6.022x10^23 molecules.

Explanation:

At stp, it has been proven that 1mole of a gas occupy 22.4L.

Therefore, option (i) is correct.

The molar mass N2 = 14.01 x 2 = 28.02g/mol

Number of mole of N2 = 1 mole

Mass of N2 =..?

Mass = mole x molar Mass

Mass of N2 = 1 x 28.02 = 28.02g.

The mass content of the balloon is 28.02g, therefore, option (ii) is wrong.

From Avogadro's hypothesis, we understood that 1 mole of any substance contains 6.02x10^23 molecules. This implies that 1 mole of N2 also contains 6.02x10^23 molecules

Therefore, option (iii) is correct.

The correct options to the question are:

Option i and option iii
