Answer:
26.8g
Explanation:
The formula of the compound given is:
Cu₂CrO₄
Given:
Number of moles = 0.11
To find the mass, we use the expression below:
Mass = number of moles x molar mass
Molar mass of Cu₂CrO₄ = 2(63.6) + 52 + 4(16) = 243.2g/mol
Now insert the parameters and solve;
Mass = 0.11 x 243.2 = 26.8g
Answer:Sodium chloride solid is not a mixture. ... It cannot be physically separated into its components, Na+ and Cl−
Explanation:Sodium chloride is formed when sodium atoms interact with chlorine atoms. When this occurs, sodium will donate an electron (which is a negatively-charged particle) to chlorine. This makes sodium slightly positive and chlorine slightly negative.
Opposite charges attract, right? So then, sodium ions will attract chloride ions and form an ionic bond. By the way, chloride is the term used to designate the anion form of chlorine. The result is a crystallized salt that has properties that are different from the two parent elements (sodium and chlorine). The chemical formula for sodium chloride is NaCl, which means that for every sodium atom present, there is exactly one chloride atom.
well what are the elments that it is wanting u to do this with (need more info about what it is asking
Answer:
28.52 L
Explanation:
First, let's calculate the density of the ocean, which is the mass divided by the volume:
d = m/V
d = 35.06/1
d = 35.06 g/L
So, for a mass of 1.00 kg = 1000.00 g
d = m/V
35.06 = 1000.00/V
V = 1000.00/35.06
V = 28.52 L
How all the data are expressed with two significant figures, the volume must also be expressed with two.
