Thank you for posting your question here at brainly. Below are the choices that can be found elsewhere:
12.88 M
<span>0.1278 M </span>
<span>0.2000 M </span>
<span>0.5150 M
</span>
Below is the answer:
<span>5 times diluted (250/50),so 2.575/5=0.515 M
</span>
I hope it helps.
You mix 35mL of 0.54M NaI with 14mL of 0.84M Pb(NO3)2.
Answer:
90g
Explanation:
We need to find the molar mass of C6H12O6. This is done below:
MM of C6H12O6 = (12x6) + (12x1) + (6x16) = 72 + 12 + 96 = 180g/mol
From the question, we obtained:
Volume = 1L
Molarity = 0.5M
Number of mole = Molarity x Volume
Number of mole = 0.5 x 1 = 0.5mol
Mass conc of C6H12O6 = number of mole x MM = 0.5 x 180 = 90g
