How many moles of n are in 0.185 g of n2o?
pickupchik [31]

The mass of N_{2}O is 0.185 g.

To calculate the number of moles first calculate the molar mass of N_{2}O .

M_{N_{2}O}=2\times M_{N}+M_{O}

Molar mass of nitrogen and oxygen is 14 g/mol and 16 g/mol respectively

Thus, M_{N_{2}O}=2\times 14 g/mol+18 g/mol=44 g/mol

Now, number of moles can be calculated from mass and molar mass as follows:

n=\frac{m}{M}=\frac{0.185 g}{44 g/mol}=0.0042 mol

Therefore, number of moles of 0.185 g N_{2}O is 0.0042 mol.

A liquid sample, with a density of .0915 g/mL has a mass of 17.7 grams.
Arlecino [84]

The relation between density, mass and volume is

Density = \frac{Mass}{Volume}

1) to calculate = volume

given:

Density = 0.0915 g/ mL

mass = 17.7 grams

formula used:

Density = \frac{Mass}{Volume}

Thus

Volume Volume = \frac{Mass}{Density} = \frac{17.7 g}{0.915 \frac{g}{mL} }  = 193.44 mL

Answer: 193.44 mL

2) the mass of sample will be

mass = density X volume = 0.0915\frac{g}{mL} X 76.5 mL = 6.99 = 7 g

Answer: 7 g

d1i1m1o1n [39]
Answer:
            <span>Formula for sodium hydroxide is represented by <u>NaOH</u>.

Explanation:
                     The reaction of Sodium oxide with water is as follow,

                               Na</span>₂O  +  H₂O    →    2 NaOH
<span>
Na</span>₂O is considered as a strong basic oxide as it contains O²⁻ which has high tendency to bind with hydrogen atoms. This reaction is an exothermic reaction and is conducted in cold water to produce NaOH.<span>
