The particles move from an area of high concentration, to an area of low concentration, until the distribution of particles is equal
Answer: 13750mg or 13.75gram
In this case, the insulin has 50mg/ml concentration with 275ml volume. To know the mass, you need to multiply concentration with volume. The calculation would be
mass= concentration x volume
mass= 50mg/ml x 275ml= 13750mg or 13.75gram
Answer:
5 cm³.
Explanation:
From the question given above, the following data were obtained:
Volume of water = 35 mL
Volume of water + Rock = 40 mL
Volume of Rock =.?
The volume of the rock can be obtained as follow:
Volume of Rock = (Volume of water + Rock) – (Volume of water)
Volume of Rock = 40 – 35
Volume of Rock = 5 mL.
Finally, we shall convert 5 mL to cm³.
This can be obtained as follow:
1 mL = 1 cm³
Therefore,
5 mL = 5 mL × 1 cm³ / 1 mL
5 mL = 5 cm³
Thus, we can say that the volume of the rock is 5 cm³.
Answer:
You also know about the mass of that sample, if you know the moles
(First option)
Explanation:
Moles = Mass / Molar mass
Moles . Molar mass = Mass
For example, I have 4 moles of H₂O
Molar mass H₂O = 18 g/m
4 m . 18 g/m = 72 g
If I have 4 moles of H₂O, I also have 72 grams of water too.
