Answer:
1.72 M
Explanation:
Molarity is the molar concentration of a solution. It can be calculated using the formula a follows:
Molarity = number of moles (n? ÷ volume (V)
According to the information provided in this question, the solution has 58.7 grams of MgCl2 in 359 ml of solution.
Using mole = mass/molar mass
Molar mass of MgCl2 = 24 + 35.5(2)
= 24 + 71
= 95g/mol
mole = 58.7g ÷ 95g/mol
mole = 0.618mol
Volume of solution = 359ml = 359/1000 = 0.359L
Molarity = 0.618mol ÷ 0.359L
Molarity = 1.72 M
5.4 M = moles of solute / 1.50 L
<span>Multiply both sides by 1.50 L to isolate moles of solute on the right. </span>
<span>8.1 mol = moles of solute </span>
4- Ag+ions thats the answer i hope its correct
Answer:
7 μl /s
Explanation:
Given data:
0.44 mL/min
μl /s = ?
Solution:
First of all we will convert the mL/min to mL/s.
we will divide the given value by 60.
0.44/60
0.007 mL/s
Now we will convert the mL/s to μl /s.
we will multiply the value with 1000.
0.007 × 1000
7 μl /s
I would tell you... but there is a lot of information... just type in online what you asked, and you will get lots of info.
