Answer:
1.667L of a 0.30M BaCl₂ solution
Explanation:
<em>Of a 0.30M barium chloride, contains 500.0mmol of barium chloride.</em>
<em />
Molarity is an unit of concentration used in chemistry defined as the moles of solute present in 1 liter of solution.
In a 0.30M BaCl₂ solution there are 0.30 moles of BaCl₂ in 1 liter of solution.
Now, in your solution you have 500mmol of BaCl₂ = 0.500 moles of BaCl₂ (1000 mmol = 1 mol). Thus, 0.500 moles of BaCl₂ are present in:
0.500 moles * (1L / 0.30 moles) =
<h3>1.667L of a 0.30M BaCl₂ solution</h3>
Silver and Gold are different as their ELEMENT charateristics. To be more precise, they both have different number of protons (which is part of their ELEMENT charateristc)
Answer:
184.3g
Explanation:
Given parameters:
Volume of acid = 42.5L
Unknown:
Mass of acid = ?
Solution:
We have to assume that this measurement was taken at rtp;
At rtp;
1 mole of a substance occupies a volume of 22.4L
Therefore,
42.5L of H₂SO₄ will have 
moles = 1.9moles
To find the mass;
Mass = number of moles x molar mass
Molar mass of H₂SO₄ = 2(1) + 32 + 4(16) = 97g/mol
Mass = 1.9 x 97 = 184.3g
