Mass in grams of 4.26 mol Si

Chemistry
2 answers:
Brrunno [24]3 years ago

Answer/ explanation :

Mass in grams of 4.26 mol of Si.

To calculate this, we use the formula

Number of mole = mass / molar mass

Since we are given the number of mole

Number of mole = 4.26mol

Mass = ?g

Molar mass of Si = 28.0855g/mol

4.26mol = mass / 28.0855g/mol

By cross multiplication,

Mass = 4.26 * 28.0855

= 119.644g

Therefore, the number of mass in gram of Si is 119.644g

Answer:

119.28g

Explanation:

Data obtained from the question include:

Number of mole of Si = 4.26 mol

Molar Mass of Si = 28g/mol

Mass of Si =?

Number of mole = Mass /Molar Mass

Mass = number of mole x molar Mass

Mass of Si = 4.26 x 28

Mass of Si = 119.28g

Ion Concentration 1. Which solution has the greatest [SO42-]: a) 0.075 M H2SO4 b) 0.15 M Na2SO4 c) 0.080 M Al2(SO4)3?
soldi70 [24.7K]

Answer:

c) 0.080 M Al₂(SO₄)₃

Explanation:

Ion [SO₄²⁻] concentration of each solution is:

a) 0.075 M H₂SO₄: <em>[SO₄²⁻] = 0.075M</em>. Because 1 mole of H₂SO₄ contains 1 mole of SO₄²⁻

b) 0.15 M Na₂SO₄: <em>[SO₄²⁻] = 0.15M</em>. Also, 1 mole of Na₂SO₄ contains 1 mole of SO₄²⁻

c) 0.080 M Al₂(SO₄)₃ [SO₄²⁻] = 0.080Mₓ3 =<em> 0.240M</em>. Because 1 mole of Al₂(SO₄)₃ contains 3 moles of SO₄²⁻.

<h3>Thus, the soluion that has the greatest [SO₄²⁻] is 0.080 M Al₂(SO₄)₃</h3>
