Answer:

Option C. 760mmHg & 0°C

Explanation:

The standard pressure = 760mmHg = 1atm = 760torr = 101325N/m2

= 101325Pa

Standard temperature = 0°C =273K

From the above, the right combination is 760mmHg and 0°C

How does population density effect population growth?

Ronch [10]

Population growth decreases as the population density increases. This may be true for non-human populations but our species has developed the ability to modify the environment to sustain a huge population size.

What mass of nitrous oxide can be formed from 48.7 g of nitrogen?

Arisa [49]

$\\ \tt\bull\rightarrowtail2 N_2+O_2\longrightarrow 2N_2O$

2mol of N_2 forms 2mol of N_2O
1mol of N_2 forms 1mol of N_2O

Moles of N_2

$\\ \tt\bull\rightarrowtail \dfrac{48.7}{14}=3.4mol$

Molar mass of N_2O=44g/mol

Mass of N_2O formed

44(3.4)=132.16g

1. Calculate how many moles of glycine are in a 130.0-g sample of glycine.2. Calculate the percent nitrogen by mass in glycine.

Alexxx [7]

Answer:

$n=1.732mol$

$\% N=18.7\%$

Explanation:

Hello!

In this case, since the molecular formula of glycine is C₂H₅NO₂, we realize that the molar mass is 75.07 g/mol; thus, the moles in 130.0 g of glycine are:

$n=130.0g*\frac{1mol}{75.07 g}\\\\ n=1.732mol$
