Answer:
4.86moles of barium sulfide are produced
Explanation:
To solve this question we need to convert the mass of barium sulfide (BaS) to moles using the molar mass of BaS:
<em>Molar mass BaS:</em>
<em>1 Ba atom = 137.3g/mol</em>
<em>1 S atom = 32.1g/mol</em>
<em>Molar mass BaS = 137.3 + 32.1 = 169.4g/mol</em>
<em />
<em>Moles in 823g of BaS:</em>
823g * (1mol / 169.4g) =
<h3>4.86moles of barium sulfide are produced</h3>
Answer:
isotopes of hydrogen are protium,deuterium and tritium
Answer:
<h3>The answer is 122.5 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 = 7 mL
density = 17.5 g/mL
We have
mass = 17.5 × 7
We have the final answer as
<h3>122.5 g</h3>
