29.2 grams of methane (carbon tetrahydride), CH4, is how

Elena-2011 [213]

Answer:

1.83moles

Explanation:

Given parameters:

Mass of methane given = 29.2g

Unknown:

Number of moles = ?

Solution:

To find the number of moles in this mass of a compound;

Number of moles = $\frac{mass}{molar mass}$

Molar mass of CH₄ = 12 + 4(1) = 16g/mol

Now;

Number of moles = $\frac{29.2}{16}$ = 1.83moles

A chemistry student needs 50.0 g of methyl acetate for an experiment. By consulting the CRC Handbook of Chemistry and Physics, t

slamgirl [31]

Explanation:

As density is defined as the mass of a substance divided by its volume.

Mathematically, Density = $\frac{mass}{volume}$

It is given that mass is 50 g and density is 0.934 $g/cm^{3}$ .

Hence, calculate the volume of methyl acetate as follows.

Density = $\frac{mass}{volume}$

0.934 $g/cm^{3}$ = $\frac{50 g}{volume}$

Volume = $53.53 cm^{3}$

or, = $53.53 ml$ (as 1 $cm^{3}$ = 1 mL)

Thus, we can conclude that the volume of methyl acetate the student should pour out is $53.53 ml$ .
