Two measurments that are the same as each other are called_____? What are they called???

1 answer:

8 0

Precision refers to the closeness of two or more measurements to each other. Using the example above, if you weigh a given substance five times, and get 3.2 kg each time, then your measurement is very precise. Precision is independent of accuracy.

a measuring cylinder contains 30cm3 of a liquid some more of the liquid is added until the liquid level reaches the 50cm3 mark t

S_A_V [24]

Answer:

1.5g/cm³

Explanation:

Given parameters:

Initial volume of the liquid = 30cm³

Final volume of the liquid = 50cm³

Mass of the liquid = 30g

Unknown:

Density of the liquid = ?

Solution:

Density is the mass per unit volume of a substance.

Density = $\frac{mass}{volume}$

volume of the liquid = final volume - initial volume = 50cm³ - 30cm³

volume of the liquid = 20cm³

Density = $\frac{30}{20}$ = 1.5g/cm³

Determine the density of an object that has a mass of 149.8 g and displaces 12.1 mL of water when placed in a graduated cylinder

Crazy boy [7]

Answer:

"12.4 g/mL" would be the right solution.

Explanation:

The given values are:

Mass of the object,

= 149.8 g

Volume of the object,

= 12.1 mL

Now,

The Density will be:

⇒ $Density=\frac{Mass}{Volume}$

On substituting the given values in the above formula, we get

⇒ $=\frac{149.8}{12.1}$

⇒ $=12.4 \ g/mL$
