Which has more mass: an armful of feathers or an armful of lead? which has more volume: a kilogram of feathers or a kilogram of
valina [46]
Mass is related to weight. It measures the resistance of the substance to acceleration when a net force is applied.
Therefore: armful of lead has more mass

volume measures the amount of 3-dimensional space that an object occupies.
Therefore: kilogram of feather has more volume as it is less dense.

density is the mass per unit volume. Since armful of lead has more mass than a handful of feathers, while kilogram of feather has more volume than a kilogram of lead.
Therefore: kilogram of lead has higher density.

A brick has a mass of 4.0 kg and the Earth has a mass of 6.0 × 1027 g. Use this information to answer the questions below. Be su
Vedmedyk [2.9K]

Answer:

a) 2.4\times 10^{24} kg is the mass of 1 mole of bricks.

b) 2.5\times 10^3 moles of bricks have a mass equal to the mass of the Earth.

Explanation:

a) Mass of brick = 4.0 kg

1 mole = N_A=6.022\times 10^{23} particles/ atoms/molecules

Mass of N_A bricks :

=6.022\times 10^{23}\times 4.0 kg=2.4088\times 10^{24} kg\approx 2.4\times 10^{24} kg

2.4\times 10^{24} kg is the mass of 1 mole of bricks.

b)

Mass of the Earth = M = 6.0\times 10^{27} kg

Mass of 1 mole of brick = m=2.4\times 10^{24} kg

Let the moles of brick with equal mass of the Earth be x.

m\times x=M

x=\frac{M}{m}=\frac{6.0\times 10^{27}kg}{2.4\times 10^{24} kg}=2.5\times 10^3

2.5\times 10^3 moles of bricks have a mass equal to the mass of the Earth.

Which pair must represent atoms of the same element?
andrew-mc [135]
Your answer is B and the element is Carbon

So what your looking for is matching isotopes. Isotopes are elements that are the same in amount of protons but different in mass meaning different number in neutrons. Because when you add the total protons and neutrons together you get your atomic mass. So this can be written as X=said element, top number above=different atomic mass, bottom number below=atomic number. Hope this help!!

Be careful because answer A has same masses but different atomic numbers so different atoms(elements)!!!
