Answer:-  1.62 moles

Solution:- At constant temperature and pressure, volume is directly proportional to the moles of the gas.

\frac{V_1}{V_2}=\frac{n_1}{n_2}

from given data, V_1 = 5.17 L, n_1 = 1.05 moles

V_2 = 8.00 L, n_2 = ?

Let's plug in the values in the formula:

\frac{5.17L}{8.00L}=\frac{1.05moles}{n_2}

On cross multiply:

n_2=\frac{8.00L(1.05moles)}{5.17L}

n_2 = 1.62 moles

So, now the toy contains 1.62 moles of the air.

How do you determine the environmental impact of human activities?
coldgirl [10]

Answer:

Environment refers to everything that surrounds an individual and interacts between them. The factors that control the environment can be biotic and abiotic.

Humans have greatly affected the environment. Some of the ways in which the environment is affected by humans are as follows-

(1) Humans have constructed industries and factories that have released a huge amount of toxic gases into the atmosphere.

(2) These harmful gases have increased the earth's global temperature. As a result of which the global warming effect has increased.

(3) The waste materials eliminated from these industries mix with the rivers and streams and pollute the water. It degrades water quality.

(4) The fossil fuels are exhausted at a very high rate.

(5) The spilling of the oils in the oceans has affected the marine species drastically.

(6) Due to the extensive mining at different places, soil fertility has decreased considerably.

(7) Cutting down trees for settlement purposes and other infrastructures.

A liquid has a density of 1.17 g/cm3, how many liters of the liquid have a mass of 3.75 kg
Luda [366]
<span>There are 1000 cm3 in 1 liters. Hence 1 liter of the liquid would weigh: 1000 cm3 x (1.17 g/cm3) = 1170 gm and there are 1000 gm in 1 kg, so we want enough liters to have a mass of 3.75 kg x 1000 gm/kg = 3750 gm Hence, # of liters = desired mass / # of gm per liter = 3750 gm / 1170 gm/liter = 3.2051282 liters</span>
