Moles = Mass(g) / ar
Moles of phosphorus = 0.859 / 31
= 0.0277096774
1 mole = 6.02 × 10^23
Atoms of phosphorus = 0.0277096774 × 6.02×10^23
=ans.
sorry i cant do the calculation. I dont have a calculator with me.
Explanation:
Two different elements have similar chemical properties when they have the same number of valence electrons in there outermost energy level. Elements in the same column of the periodic table have similar chemical properties.
Answer:
The answer is
<h2>34.02 g</h2>
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 of lead = 3 mL
density = 11.34 g/mL
The mass of the lead is
mass = 3 × 11.34
We have the final answer as
<h3>34.02 g</h3>
