<span>Heavy metals like mercury enter waterways by industrial dumping and poor regulatioin of effluent, and they also enter soil through a similar manner, in which waste is disposed of imporperly. Another source of heavy metals are the gases leaving industry carrying these metals. The metals fall as a solid on to soil and water ways. Therefore, the answer is D.</span>

If a lab requires each a lab group (3 students) to have 25 ml of a solution and it takes 15 grams of AgNO₃ cuprous nitrate, to m
pochemuha

Answer:

0.375 grams are needed to make 25 mL solution.

Explanation:

Mass of AgNO_3 cuprous nitrate required to make 1 l of solution = 15 g.

1 L = 1000 mL

Mass of AgNO_3 cuprous nitrate required to make 1000 mL of solution = 15 g

Mass of AgNO_3 cuprous nitrate required to make 1 mL of solution:

=\frac{15}{1000} g

Mass of AgNO_3 cuprous nitrate required to make 25 mL of solution:

=\frac{15}{1000} \times 25 g=0.375 g

0.375 grams are needed to make 25 mL solution.

There are 85.63 g of CO2 gas in a container maintained at STP. How many liters of CO2 are there in that container?
konstantin123 [22]

Answer:

V = 48.64 L

Explanation:

Given data:

Mass of CO₂ = 85.63 g

Temperature = 273 K

Pressure = 1 atm

Volume of CO₂ = ?

Solution:

Number of moles of CO₂:

Number of moles = mass/molar mass

Number of moles = 85.63 g / 40 g/mol

Number of moles = 2.14 mol

Volume in Litter:

PV = nRT

R = general gas constant = 0.0821 atm.L/mol.K

1 atm× V = 2.14 mol ×0.0821 atm.L/mol.K  ×273 K

V = 48.64 atm.L / 1 atm

V = 48.64 L
