Answer:
volume = mass/density
Here, volume = 80g/1.59gcm-3 → 50.314 cm3
Explanation:
Answer:
Atoms are made up of protons, neutrons, and electrons. The mass of an atom is determined by the total number of neutrons and protons in the nucleus. The difference between an atom and an ion is the number of electrons. The change of electrons does not change the mass because electrons have a negligible mass. In other words, the mass of electrons is so small, it is considered insignificant.
Explanation:
In Physics, force is defined as: The push or pull on an object with mass that causes it to change its velocity. Force is an external agent capable of changing the state of rest or motion of a particular body. It has a magnitude and a direction. ... The SI unit of force is Newton(N).

Answer:
%Sgr = 1% (1 sig.fig.)
Explanation:
mass water = 350ml x 0.975g/ml = 341.25g
mass sugar added = 4g
solution mass = 341.25g + 4g = 345.25g
%sugar = (4g/345.25g)·100% = 1.1586% ≅ 1% (1 sig.fig)
