Answer:

Pressure of gas A = 544.324 kPa

Pressure of gas B = 2217.784 kPa

Explanation:

Data provided in the question:

Total volume of the cylinder, V = 5.55 L = 0.00555 m³     [1 m³ = 1000 L]

Moles on gas A, n_a = 1.21 mol

Moles on gas A, n_b = 4.93 mol

Temperature, T = 27.3°C = 27.3 + 273 = 300.3 K

Now,

Pressure = \frac{nRT}{V}

here,

R is the ideal gas constant = 8.314 J/mol.K

Therefore,

Pressure of gas A = \frac{n_aRT}{V}

= \frac{1.21\times8.314\times300.3}{0.00555}

= 544324.32 Pa

= 544.324 kPa

Pressure of gas B = \frac{n_bRT}{V}

= \frac{4.93\times8.314\times300.3}{0.00555}

= 2217784.22 Pa

= 2217.784 kPa

If the trend changed toward traditional (pre-World War II) families, how would that affect women’s rights?
LUCKY_DIMON [66]

If the trend changed toward traditional (pre-World War II) families, the women’s rights are employment in manufacturing sector.

<h3>What is World war?</h3>

The war between two countries to take over each other's kingdom using weapons to kill each other.

Before the world war, the army needs armor, weapons, guns and tanks. Their manufacturing is only possible with many workers to work for long hours. If the men are not enough, then women are given opportunities to work with them.

Thus, the women’s rights are employment in manufacturing sector when trend changed traditional families.

The ocean's level is currently rising at about
chubhunter [2.5K]

Answer:

The sea level will be 5m higher in 1667 y (years)

Explanation:

From the question, the rate at which the ocean's level is currently rising is about 3mm per year.

First, we will convert mm (millimeter) to m (meter)

1 mm = 0.001 m

Then,

3 mm = 3 × 0.001 m

= 0.003m

That is, the rate at which the ocean's level is currently rising is about 0.003m per year.

Now, to determine how long it will take for the ocean's level be 5 m higher than now at the given rate,

If the ocean rises 0.003 m in 1 year, then

the ocean will rise 5 m in x years

x = (5 m × 1 year) / 0.003 m

x = 5 / 0.003

x = 1666.67 years

x ≅ 1667 years

Hence, the sea level will be 5m higher in 1667 y (years)
