Answer:
2.676e22 atoms of Hydrogen
Explanation:
Knowing the density of water is 1g/ml, 1(g/ml)*0.4ml=0.4 grams of H2O. Knowing that there are 16 grams of H2O in 1 mole of H2O, we can set up a unit conversion of 0.4 Grams H2O * =
2.676e22 atoms of Hydrogen.
The correct answer is letter D
Answer:
Group of highly-reactive chemical elements. The alkali metals are a group (column) in the periodic table consisting of the chemical elements lithium (Li), sodium (Na), potassium (K), rubidium (Rb), caesium (Cs), and francium (Fr).
Answer:
<h3>The answer is 110.16 g</h3>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
volume = 34 mL
density = 3.24 g/mL
The mass of the liquid is
mass = 3.24 × 34
We have the final answer as
<h3>110.16 g</h3>
