To how many significant figures can you report your measurement of the mass the nacl sample?

1 answer:

5 0

<span>Sodium chloride, NaCl, sample are usually used in many laboratory testings and experiments. The mass required for samples are usually just below 10 g. The most accurate readings for this mass is through which there are 2 decimal places. Thus, the highest number of significant figures that can be reported for such is only 4. </span>

What is the density of chlorine gas (MM = 71.0glmol) at 1.50 atm and 25.0C

IrinaVladis [17]

Answer: D=4.35g/L

Explanation:

The formula for density is $D=\frac{M}{V}$ . M is mass in grams and V is volume in liters.

Since we are give pressure and temperature, we can use the ideal gas law to find moles/volume. FInding moles/volume would give us the base for density. All we would have to do is convert moles to grams.

Ideal Gas Law: PV=nRT

$\frac{n}{V} =\frac{P}{RT}$
