You can apply Charles' Law.
V1= 5.00 (L)
T1= 92.3 + 273 = 365.3 (K)
T2= -37 + 273 = 236 (K)
V2 = ? (L)
We have: V1/T1 = V2/T2
--> V2= (V1*T2)/T1 = (5*236)/365.3 = 3.23 (L)
Answer:
A Balanced Atom
Most nuclei also contain neutrons. Perhaps the most essential characteristic of a proton is its positive electrical charge. This charge is equal in magnitude to the negative electrical charge of the electron, which means that the charge of one proton balances out the charge of one electron.
Explanation:
Measuring density is very important for many different industries because the density measurement will help determine the characteristics of a material, for example, whether the material will float or sink. Knowing the density of a material helps in determining the mass and volume of a material, all of which are extremely important measurements in all industries.

The answer is letter b. from the sunlight. Plants are also referred as producers. Typically, plants gets their energy from the sun, wherein it helps them produce their own food, through the sunlight, the carbon dioxide present, the process wherein the producers undergo is known as photosynthesis.
The question is missing the concentration of the lactic acid solution. You also need the molar mass of the lactic acid (or its molecular formula to calculate it)
For example, the question should read how many grams of lactic acid (C3H6O3) are in 1 liter of 0.5 M solution of lactic acid?
Now I can teach you how to calculate the mass in grams of lactic acid.
1) number of moles, n
M = n / V => n = M*V = 0.5 M * 1 l = 0.5 moles
2) molar mass of C3H6O3
C3H6O3: 3* 12g/mol + 6* 1g/mol + 3*16g/mol = 90 g/mol
3) mass in grams = number of moles * molar mass
mass in grams = 0.5 mol * 90 g/mol = 45 g
Answer: 45 g
