Ответ:
2.28 M
Explanation:
Using the formula as follows;
C1V1 = C2V2
Where;
C1 = initial concentration (M)
C2 = final concentration (M)
V1 = initial volume (L)
V2 = final volume (L)
According to the information given in this question;
C1 = 0.95M
C2 = ?
V1 = 0.60L
V2 = 0.25L
Using C1V1 = C2V2
0.95 × 0.60 = C2 × 0.25
0.57 = 0.25 C2
C2 = 0.57 ÷ 0.25
C2 = 2.28 M
Ответ:
MgAgN
and 9.8 m/s^2 is the acceleration of gravity, commonly abbreviated as ‘g’
If you take out the ‘g’s from the periodic table equation(bc the question says 9.8m/s^2 is silent) it spells MAN
So the question could be “Will you be my man?”
