Could volume by displacement be used to determine the volume of a lump of rock salt? Explain would be nice

Yes it could, but you'd have to set up the process very carefully.
I see two major challenges right away:

1).  Displacement of water would not be a wise method, since rock salt
is soluble (dissolves) in water.  So as soon as you start lowering it into
your graduated cylinder full of water, its volume would immediately start
to decrease.  If you lowered it slowly enough, you might even measure
a volume close to zero, and when you pulled the string back out of the
water, there might be nothing left on the end of it.

So you would have to choose some other fluid besides water ... one in
which rock salt doesn't dissolve.  I don't know right now what that could
be.  You'd have to shop around and find one.

2).  Whatever fluid you did choose, it would also have to be less dense
than rock salt.  If it's more dense, then the rock salt just floats in it, and
never goes all the way under.  If that happens, then you have a tough
time measuring the total volume of the lump.

So the displacement method could perhaps be used, in principle, but
it would not be easy.

La etiqueta de una bebida transparente con un ligero toque anaranjado indica que contiene aga con un 15 porciento de zumo de nar
Brilliant_brown [7]

<u>Respuesta:</u>

16 gramos de vitamina C y 8 gramos de colorantes.

Explanation:

Debemos multiplicar el porcentaje de cada componente por la cantidad total (100 %) de zumo.

800 g de zumo = 100%

- Tenemos un 2 porciento (2 en 100 o 2/100) de vitamina C. Por lo tanto, la cantidad en gramos de vitamina C es:

2/100 x 800 g = 16 g

- Tenemos un 1 porciento de colorantes en el zumo (1/100). Por lo tanto, la cantidad en gramos de colorantes es:

1/100 x 800 g = 8 g

A block of metal has a volume of 14.0in3 and weighs 5.26lb .
natulia [17]
Mass of block, m = 5.26 lb  
1 lb = 453.592 g
 5.26 lb = 2385.896 g
V = 14 in3
 1 in = 2.5 cm
 1 in3 = 15.625 cm3
 14 in3 = 218.75 cm3


Density = mass/volume
 = 2358.896 / 218.75
 = 10.783 g/cm3
