Mass/volume
In order to find density, you need to divide mass/volume
Answer:
conceiving a child who is a bone marrow match to a living child.
Explanation:
3.00 M means 3.00 mol/L. So if you want 500 mL=0.5 L, it needs 3.00 mol/L * 0.5 L = 1.50 mol. For NaCl, the molar mass is 23+35.5=58.5 g/mol. So the amount of NaCl needed is 1.50*58.5=87.75 g. So the answer is 87.75 grams.
Hey there!:
We know that :
pH = - log [ H₃O⁺ ]
pH = - log [ 8.70 x 10⁻⁵ ]
pH = 4.06
Therefore pH is 4.06
I hope this will help !
