I think the answer is C. An element or compound that cannot be physically separated. Sorry if im wrong.
I think the awnser to your question is C
Na₃PO₄ -----> 3Na(+) + PO₄(3-)
y-y.......................3y...........y
3y = 1.2
y = 0,4M
Na₃PO₄ -----> 3Na(+) + PO₄(3-)
0,4-0,4..............1,2..........0,4
0.........................1,2..........0,4
C = n/V
n = C×V
n = 0,4×0,65L
n = 0,26 mol Na₃PO₄
mNa₃PO₄: (23×3)+31+(16×4) = 164 g/mol
164g ----- 1 mol
Xg -------- 0,26 mol
X = 164×0,26
X = 42,64g Na₂SO₄
Answer:
1 cm/s
Explanation:
From the question given above,
the student is trying to convert 0.010 m/s to a number in cm/s.
Thus, we can convert 0.010 m/s to cm/s as illustrated below:
Recall:
1 m/s = 100 cm/s
Therefore,
0.010 m/s = 0.010 m/s × 100 cm/s ÷ 1 m/s
0.010 m/s = 1 cm/s
Therefore, 0.010 m/s is equivalent to 1 cm/s
