So the molarity equation is moles of solute/liters of solution. so i’m pretty sure the answer should be 0.63/0.70= .9
Yes. There are the same number on either side of the reaction.
Answer:
2. carbon
Explanation:
carbon should be the answer
Answer:
See below.
Explanation:
<h3>CoSO4 + Pb(NO3) 2 = Co(NO3) 2 + PbSO4</h3>
<em>C = 0,75 mol/dm³</em>
<em>V = 500mL = 500cm³ = 0,5dm³</em>
C = n/V
n = 0,75×0,5dm³
<u>n = 0,375 moles</u>
<em>M NaCl: 23+35,5 = 58,5g</em>
1 mole ---------- 58,5g
0,375 ----------- X
X = 0,375×58,5
<u>X = 21,9375g NaCl</u>
