Answer:
B) 3.0 g/mL
Explanation:
density formula: mass/volume
15/5=3
There are 1000 mg in 1 gram.
3.76/1000 = 0.00376
10^-3 = 0.001
0.001 x 3.76 = 0.00376
Answer is
3.76 x 10^-3
Answer:
0.217 M NaOH
Explanation:
M1V1 = M2V2
M1 = 0.312 M HCl
V1 = 17.4 mL HCl
M2 = ?
V2 = 25.0 mL NaOH
Solve for M2 --> M2 = M1V1/V2
M2 = (0.312 M)(17.4 mL) / (25.0 mL) = 0.217 M NaOH
An example would be that they can reproduce just like anything else that is living
