120g

------ = 17.11111g/mL

7mL

density = mass/volume =kg/m 3

1000ml = 1000cm3

7ml=7cm3

7ml = 0.000007m3

120g=0.12Kg

density =0.12/0.000007 = 17142.86kg/m3

realisticaly though your talking about a teaspoon (7ml) of something with a mass of 120g.

are you sure your question is correct because even lead wouldn't have this much mass

As the formula for density is mass divided by volume so we will divide 28g by 7mL which gives us 4g which is the density of an object

the density is 4g/ml3.

28grams/7ml = 4grams/ml

17.1429 gm/cm3 (rounded)

9577g

It is equal to 0.0617 pounds approximately. Kilogram is the metric unit and pound is the imperial unit for mass. 1 Kilogram is 2.204 pounds. So we multiply kg by 2.204 to get the equivalent pounds.

Same as 28g of cast-iron: 1 (One). 454g = 1lb.

It's not possible to tell you without knowing what substance you are converting. There is no standard conversion of weight units to volume units (or volume to weight, for that matter), because all ingredients have different densities. This would mean that any standard conversion would be inaccurate for many substances. For example, a cup of lead (Pb) will weigh more than a cup of chocolate mousse will. Likewise, 100g of lead will require fewer cups/tablespoons/teaspoon than 100g of feathers will require. The different densities of the ingredients mean that there is no standardised conversion for ANY weight (ounces/grams/kg) units to ANY (cups/tbl/tsp) volume units. Please state which substance you wish to convert, in order to get an accurate conversion.

An adult house mouse on Pluto would range from .938 grams - 1.876 grams. This is because an adult house mouse usually weighs 14g - 28g. The force of gravity of Pluto is 0.067. Just multiply the weight and force of gravity and you get the weight on that planet.

There are 28.3495231 grams to every ounce of weight.

Density is an intensive physical property. It is the mass per unit of volume. The formula is Density = mass/volume. So if an object has a mass of 28g and a volume of 7cm3, the density would be 28g/7cm3 = 4g/cm3.

You must mean it occupies 36cm3. D = M/V, so 992g/36cm3 = about 28g/cm3.

The difference between the weights (grams) of the empty cylinder, and with the liquid gives you the weight of the liquid. Divide that by 30 to get the density of the liquid in g/ml

Its not so much density that would give an object a higher gravitational pull, but overall mass. Take the sun as an example, its overall mass is 99.85% of the total solar systems mass and with that has a huge gravitational pull, keeping all of the planets and other objects in orbit around it. At the surface, the pull is around 28g, 28 times that of earths surface gravity. The average density of the sun is only around 1.4 g/cm3 though, compared with Earths average density of around 5.5 g/cm3, since the sun is mainly made from hydrogen and helium, while the earth contains a high percentage of iron, nickel and other dense elements. The sun clearly has a higher gravitational pull though, its not really the density, but the shear amount of mass that determines the gravitational pull (earths mass is only about 0.0003% of the total solar systems mass.)

It would be 7 x 22.4 litre ie 156.8 litre.

electron 9.11X10-28g then proton with 1.67X10-24g then alpha particle with four times the mass of a proton

Ok, so we have... Zn + CuCl2 -> ZnCL2 + Cu And we are given that we have 28g of Zn (Zinc). But the question calls for moles of ZnCl2. So, the first step is to convert grams to moles of Zn. We will need to find the AMU (Atomic Mass Units) that a Zn atom's mass. A Zn atom has a mass of 63.546 AMU. Now, we take the given mass and divide it by the mass of the atom to get the moles of reactant we have. 28g/63.546AMU≈ .4406257moles If your teacher/ professor cares about sig figs, then it's .44 because you only have two sig figs from the given from the given mass of Zn (28g). Now, the easy part. What is the ratio of Zn atoms on the reactant side to Zn atoms on the product side? 1:1 And since we have excess CuCl2 Nothing else limits the reaction. So, .44 (or how ever far your teacher wants you to round) moles of Zn reactants in a ideal environment (you will learn later that no reaction is 100% and that there are reactants always left over and how to solve for that) produces .44 moles of ZnCl2.
