Explanation:
for the first one go to the website mathaway and just put the equation in and you would press graph.
Hey there!
MgCl₂
Find molar mass of magnesium chloride.
Mg: 1 x 24.305
Cl: 2 x 35.453
--------------------
95.211 grams
One mole of magnesium chloride has a mass of 95.211 grams.
We have 2.40 moles.
2.40 x 95.211 = 228.5
To 3 sig figs this is 229.
The mass of 2.40 moles of magnesium chloride is 229 grams.
Hope this helps!
Solution:
<span>1 L of solution and 1.03 g/mL = 1030 g/L </span>
<span>
1030 g/L time 10.5%
= 108.15 g of glucose/L</span>
And
<span>=108.15 g / 180.16 g/mol
= 0.6003 moles in 1L </span>
<span>=or 0.600 mol/kg</span>
The greater the surface area between reactants, the greater the rate of the reaction.
