Answer:

2.0 m nacl

Explanation:

Depression of freezing point is given by the equation:

ΔTf = m. Kf. i

where i is the Van't Hoff factor, m is the molality, and Kf is the freezing point depression constant.

As per the formula, depression of freezing point is directly proportional to the molality. 2.0 m NaCl has the highest molaity and will have the maximum depression in freezing point. As a result it will also have the lowest freezing point.

The more particles (ions or molecules) that you can put into solution, the lower the freezing point.

the answer is E. 2.0 M nacl

Determine the mass of SO₂ that contains 6.075 × 10^26 S atoms.

Misha Larkins [42]

Avogadro's law states that in a mole of any substance, there are $6.022 \times 10^{23}$ atoms. This means that in the given sample, there are

$\frac{6.075 \times 10^{26}}{6.022 \times 10^{23}}=1008.8010627 \text{ mol}$

The atomic mass of sulfur is 32.06 amu.
The atomic mass of oxygen is 15.9994 amu.

So, the atomic mass of sulfur dioxide is

$32.06+2(15.9994=64.0588 \text{ g/mol}$

Therefore, the mass is:

$(64.0588)(1008.8010627)=\boxed{64620 \text{ g (to 4 sf)}}$
