A sample of a substance has a volume of 60.5ml and a density of 1.20g/ml what is density of magneis

erica [24]

Answer:

m = 72.6 grams

Explanation:

Given that,

The density of the substance uis 1.2 g/mL

Volume, V = 60.5 mL

We need to find the mass of the substance. Density is equal to mass divided by its volume. So, it can be given by :

$d=\dfrac{m}{V}\\\\m=d\times V\\\\m=1.2\ g/mL\times 60.5\ mL\\\\m=72.6\ g$

So, the mass of the substance is 72.6 grams.

why are the theoretical density values of brass, bronze, and steel reported as a range of densities? how can you categorize thes

Julli [10]

Answer:

Theoretical density values

brass- $8.4-8.73 gm/cm^3$

bronze- $8.73 g/cm^3$

steel- $7.75 - 8.05 gm/cm^3$

Explanation:

All of these substances are alloys (a substance made from melting two or more substances, one of them usually being a metal). Brass is a combination of copper and zinc, bronze is mostly copper, tin and other non-metals as well and steel is majorly made up of iron and copper. These alloys have various uses and varying importance in different kinds of industries.

Pipettes are used when measuring the volumes of liquids with high degree of precision. The following volumes were obtained durin

never [62]

Answer:

0.075

Explanation:

First obtain the mean of the measurement;

Mean = 10.15 + 9.95 + 9.99 + 10.02/4 = 10.03

Then obtain d^2= (mean-score)^2 for each score;

(10.15-10.03)^2 = 0.0144

(9.95-10.03)^2 = 0.0064

(9.99-10.03)^2 = 0.0016

(10.02-10.03)^2= 0.0001

∑d^2= 0.0144 + 0.0064 + 0.0016 + 0.0001

∑d^2= 0.0225

Variance = ∑d^2/N = 0.0225/4 = 0.005625

Standard deviation= √0.005625

Standard deviation= 0.075
