No.
It is 7/200.
35g^2h-15gh^2
It is a term used to denote the part, or fraction, of something that actually has mass, or the amount of a specific element within a compound. For example, think of a jar full of marbles. There is some space in between the marbles that is empty, yes it contains air but for the purpose of this example consider it to be empty space. If the total volume of the jar the marbles occupy is 95%, then you could say that the mass fraction in the jar is 95% of the total volume. You could also think of this in another way. Compounds are made up of various elements. Say you have common bleach, sodium hypochlorite, NaOCl, and you want to know what % of bleach is actually chlorine. The total weight of a molecule of NaOCl is 74 g/mol. Since Cl weighs 35g/mol the mass fraction of chlorine in NaOCl is 35/74 *100% or 47.29%.

volume of 35g
density = mass ÷ volume= 35g ÷ 25 cm3= 1.4 g/cm3 (= 1.4 gcm-3)Density = Mass/Volume = 35.0/25.0 = 1.4 g per cm3

Calculate the mass of water (density: 1 g/ml) --> 245 ml * 1 g/ml = 245 g of water wt % = 35 g / (35g + 245g) * 100% = 12.5%
Divide the mass of the object by it's volume in your question 350 g / 95 cm3 to find density. Your answer will be 3.7 g cm-3 ( grams per cubic centimeter).
The mass of the liquid is 35 g. This is calculated by subtracting the container's mass (150 g) from the total mass of the container plus the liquid (185 g).
Assuming it is a round marble (spherical actually) one first has to weigh it. Next one has to measure its diameter using a micrometer or a vernier scale. Halve the diameter to obtain the radius R. The volume can then be calculated by using the equation 4/3 x pi x R x R x R. Pi can be taken as being 22/7 or 3.142 Density is mass divided by volume and on the surface of the earth, mass and weight are usually regarded as being the same (not strictly true but near enough)

A common item that weighs around 35g is a large paper clip.
35 mg = 0.035 gTo convert from mg to g, divide by 1000.
