What is the base metric unit for measuring volume?

uranmaximum [27]

I got this idk if it's correct: For measuring large distances, the kilometer (103 or 1000 meters) is often used. The basic unit of volume in the metric system is the liter (l). The most common derived unit is the milliliter (ml) (10-3 or 1/1000 of a liter). The volume of a milliliter is equal to the volume of a cube 1 centimeter per side.

emmainna [20.7K]

<u>Answer:</u> The correct answer is Option 1, Option 2 and Option 3.

<u>Explanation:</u>

A base is defined as the substance which releases hydroxide ion when dissolved in water.

For the given options:

<u>Option 1:</u> $NH_3$

When ammonia is dissolved in water, it produces ammonium hydroxide which forms a basic solution.

$NH_3+H_2O\rightarrow NH_4OH$

<u>Option 2:</u> $Na_2O$

When sodium oxide is dissolved in water, it produces ammonium hydroxide which forms a basic solution.

$Na_2O+H_2O\rightarrow 2NaOH$

<u>Option 3:</u> $LiOH$

When lithium hydroxide is dissolved in water, it produces aqueous lithium hydroxide which forms a basic solution.

$LiOH+H_2O\rightarrow LiOH(aq.)$

<u>Option 4:</u> $P_4O_{10}$

When phosphorus pentoxide is dissolved in water, it produces phosphoric acid which forms an acidic solution.

$P_4O_{10}+6H_2O\rightarrow 4H_3PO_4$

Hence, the correct answer is Option 1, Option 2 and Option 3.
