The independent variable is the type of liquid and the dependent variable growth of the plants.

<h3>What is an experiment?</h3>

An experiment is used to establish the relationship between causes and effect in each of the following cases, let us determine the dependent and independent variable.

1) The independent variable is the type of liquid and the dependent variable growth of the plants. The constants are the plants and the land. A valid hypothesis is; "The growth of the plants depends on the type of liquid used to water the plants"

2) The independent variable is the mode of transport and the dependent variable is the time taken to reach the market. The constant is the distance covered. A valid hypothesis is; "The time taken to arrive at the grocery store depends on the mode of transport used"

3) The independent variable is the kind of app and the dependent variable is the  battery life. The constant is the phone used while the hypothesis is; "Certain apps delete the battery faster than others"

What is the mass of 1.2 x 1023 atoms of arsenic?
Gre4nikov [31]

Answer:

14.93 g

Explanation:

First we <u>convert 1.2 x 10²³ atoms of arsenic (As) into moles</u>, using <em>Avogadro's number</em>:

  • 1.2 x 10²³ atoms ÷ 6.023x10²³ atoms/mol = 0.199 mol As

Then we can<u> calculate the mass of 0.199 moles of arsenic</u>, using its<em> molar mass</em>:

  • 0.199 mol * 74.92 g/mol = 14.93 g

Thus, 1.2x10²³ atoms of arsenic weigh 14.93 grams.
