Calculate the molar mass for NaOH

Chemistry
1 answer:
Makovka662 [10]3 years ago
8 0

Answer:

39.998

Explanation:

Hello, have a periodic table handy!

Molar mass is the molecular weight of a compound; sum of all of the mass in grams (from the periodic table) from each and specific atom.

In the periodic table, the molecular weight of an atom is usually shown on the bottom of the element.

In NaOH, there are three atoms in that compound. Na (sodium), O (oxygen), and H (hydrogen).

For Na, the molecular weight is 22.99

For O, the molecular weight is 16.00

For H, the molecular weight is 1.008.

Add all of those values up together to get the molar mass of NaOH being 39.998

The volume of a gas that occupies 9 L at a temperature of 325K is 12.46L.

<h3>How to calculate volume?</h3>

The volume of a given gas can be calculated using the following Charle's law equation:

V1/T1 = V2/T2

Where;

  • T1 = initial temperature
  • T2 = final temperature
  • V1 = initial volume
  • V2 = final volume

  • V1 = 9L
  • V2 = ?
  • T1 = 325K
  • T2 = 450K

9/325 = V2/450

325V2 = 4050

V2 = 4050/325

V2 = 12.46L

Therefore, the volume of a gas that occupies 9 L at a temperature of 325K is 12.46L.

A hot air balloon can have a volume of 2950 cubic meters (2.95 ✕ 106 liters) and operate at temperatures up to 250°F (121°C). As
TiliK225 [7]

Answer:

2.64 × 10⁶ g

Explanation:

We can find the mass of air using the ideal gas equation.

P.V=n.R.T=\frac{m}{M} .R.T

where,

P is the pressure (P = 1.00 atm)

V is the volume (V = 2.95 × 10⁶ L)

n is the number of moles

R is the ideal gas constant (0.08206atm.L/mol.K)

T is the absolute temperature (121°C + 273 = 394 K)

m is the mass

M is the molar mass (28.09 g/mol)

m=\frac{P.V.M}{R.T} =\frac{1.00atm \times 2.95 \times 10^{6} L \times 28.97g/mol}{(0.08206atm.L/mol.K) \times 394 K } =2.64 \times 10^{6} g
