<span>You know how when you dilute something, you would divide by the volume, and when you take an aliquot, you would multiply by the volume? Well, since you're working backwards, you do the opposite operations.
3.17E-6 M (150.0 mL / 10.00 mL) = 4.76E-5 M (150.0 mL / 10.00 mL) = 7.13E-4 M (150.0 mL / 10.00 mL) = 1.07E-2 M (150.0 mL / 10.00 mL) = 0.160 M
So the original stock was a 0.160 M HBr solution.</span>
Does mass<span> alone provide no information about the amount or size of a measured quantity? No, we need combine </span>mass<span> and </span>volume<span> into "one equation" to </span>determine<span> "</span>density<span>" provides more ... </span>g/mL<span>. An </span>object has<span> a mass of </span>75 grams<span> and a volume of </span>25 cc<span>. ... A </span>certain object weighs 1.25 kg<span> and </span>has<span> a </span>density of<span> </span>5.00 g/<span>mL</span>
Step 1
% by mass:
Mass of solute ---- 100 of solution
Mass of solution = mass of solute + mass of solvent = 55.0 g + 137 g = 192 g
Solute = NH4Cl
Solvent = Water (H2O)
-----------------------------
Step 2
Procedure:
55.0 g NH4Cl --------- 192 g solution
X ---------- 100 g solution
X = 29 g NH4Cl = 29 % by mass approx.
Answer: 29 % by mass
Answer:
Gravity pulls all sides equally forming a ball
Answer:
24+74+61+29+38+27+68+54= 375
then divide by the number of numbers in this case 8 so;
375/8= 46.875
<h2>that's the median
46.875</h2>
