A student obtained a clean, dry, glass-stoppered flask. He weighed the flask stopper and found the total mass to be 32.634g. He

shutvik [7]

Answer :

The mass of water is, 26.845 g

The volume of water is, 26.92 mL

The volume of flask is, 26.92 mL

Explanation : Given,

Mass of flask stopper = 32.634 g

Mass of water and flask stopper = 59.479 g

Density of water = 0.9973 g/mL

First we have to calculate the mass of water.

Mass of water = Mass of water and flask stopper - Mass of flask stopper

Mass of water = 59.479 g - 32.634 g

Mass of water = 26.845 g

Thus, the mass of water is, 26.845 g

Now we have to calculate the volume of water.

$\text{Volume of water}=\frac{\text{Mass of water}}{\text{Density of water}}$

$\text{Volume of water}=\frac{26.845g}{0.9973g/mL}$

$\text{Volume of water}=26.92mL$

Thus, the volume of water is, 26.92 mL

Now we have to calculate the volume of flask.

Volume of flask = Volume of water = 26.92 mL

Rainwater has a ph below 7 because raindrops absorb co2 which can react with water to form carbonic acid.

makkiz [27]

This statement is true. Pure water has a neutral pH of 7. However, the atmosphere is a mixture of gases, which includes carbon dioxide among others. When it interacts with carbon dioxide, this reaction occurs:

H₂O + CO₂ → H₂CO₃

The product is carbonic acid which is a weak acid. Because the pH of an acid is below 7, the rain would also have a pH below 7.
