(1 in= 2.54 cm and 1 lb = 453.6 g) 3. An object weighing 1.840 kg has a volume of 0.0015 m³. What is the density of the object in g/cm³. 4. What is the density (g/mL) of an object that has a mass of 14.01 grams and, when placed into a graduated cylinder, causes the water level to rise from 25.2 mL to 33.6 mL?

00:01 Hello students, let's understand this problem.

00:04 In this we have to find out the in some parts are given and some we have to find out the mass in some volume or density.

00:11 So there is a relation between density, mass and volume.

00:15 So density is equal to mass upon volume.

00:22 So in all the given all the parts that is given in the question we have to find some of these parameters.

00:31 So in the first part, mass is given, mass is given which is equal to 300 gram and then density is given which is equal to 13 .6 gram per centimeter cube.

00:47 So by applying this formula we have to find out the volume.

00:51 So volume is equal to mass, mass upon density.

01:00 So mass is equal to 300 gram.

01:03 And density is equal to 13 .6 gram per centimeter cube.

01:08 So from here we get a volume which is equal to 22 .06 centimeter cube.

01:15 But in the question it is given that volume should be found in the liter.

01:20 So one centimeter cube is equal to 0 .001 liter.

01:26 So volume v is equal to 22 .06 multiply by 0 .001 liter.

01:32 So when we multiply this value we get a volume in liter which is equal to 0 .022 liter.

01:40 So by this we can get answer volume in liter.

01:45 Now and the next part in the next part density is given.

01:50 Density is given.

01:52 So density row is given which is equal to 455 pound per feet cube and volume is given.

02:01 Volume is given which is equal to 9 .00 centimeter cube.

02:07 So firstly we have to convert this density into gram per centimeter cube.

02:13 So one feet is equal to 2 .54 centimeter and one pound is equal to 453 .6 gram.

02:25 So density is equal to so density is equals to.

02:33 455 multiply by 453 .6 gram upon 2 .54 centimeter cube.

02:42 So when we calculate this, we get a density, which is equal to 1 -260 gram per centimeter cube.

02:51 Now substitute these values in the formula in order to find out the mass.

02:56 So mass is equal to density into volume...
