A loaf of bread has a volume of 700 cm3 and a mass of 420 g. what is the density of the bread?

Chemistry

joja [24]3 years ago

We know that the equation for density is:

D=\frac{m}{V}

where D is the density, m is the mass in g, and V is the volume in either mL or cubic centimeters.

So then, given two of the variables, we can solve for density:

D=\frac{420g}{700cm^{3}}

D=\frac{0.6g}{cm^{3}}

Therefore, the density of the bread is 0.6g per cubic centimeter.

PLEASE HELP AND EXPLAIN!Calculate the energy required to heat 187.0 g of ammonia from 36.1 °C to 52.9 °C. Assume the specific he
Alenkinab [10]

Answer:

E=1.48x10^4J

Explanation:

Hello!

In this case, since the energy implied in a heating process is computed by using the following equation:

E=mC(T_f-T_i)

Whereas m is the mass, C the specific heat and T the temperature. In such a way, by plugging in the given mass, specific heat and temperatures, we obtain the following energy:

E=187.0g*4.703\frac{J}{g\°C} (52.9\°C-36.1\°C)\\\\E=1.48x10^4J

Considering that the specific heat can by used by unit of °C or K because their difference is equivalent.

Regards!

If you have a gold chain that weighs 80.7 grams, what is the volume of the chain?​
just olya [345]

The volume of the gold chain is 4.18 cm³

<h3>What is density? </h3>

The density of a substance is simply defined as the mass of the subtance per unit volume of the substance. Mathematically, it can be expressed as

Density = mass / volume

With the above formula, we can determine the volume of the chain. Details below:

<h3>How to determine the volume of the gold chain</h3>

The following data were obtained from the question:

  • Mass of gold = 80.7 g
  • Density of gold = 19.3 g/cm³
  • Volume of gold chain =?

Density = mass /volume

Cross multiply

Density × volume = mass

Divide both sides by density

Volume = mass / density

Volume of gold chain = 80.7 / 19.3

Volume of gold chain = 4.18 cm³

Specify the number of protons, neutrons, and electrons in the neutral atom bromine-80.
jolli1 [7]
  80 equals the mass number. In the periodic table, the atomic number of Bromine is 35. The atomic number equals the number of protons.
  80-35= number of neutrons (mass-protons)
So, we have P=35   N=45
Furthermore, since the atom is neutral that must mean that the number of electrons equals the number of protons.
e=35
