69kg \ \ \rightarrow \ \ 100\%\\
x\ \ \ \ \ \ \ \rightarrow \ \ 3 \%\\\\\
x=\frac{3\%*69kg}{100\%}=2,07kg\\\\\\
1kg \ \ \ \ \ \ \ \rightarrow \ \ \ 2,2 \ pounds\\
2,07kg \ \ \rightarrow \ \ \ x\\\\
x=\frac{2,07kg*2,2pounds}{1kg}=4,554pounds

What is the<br> mass of 1.82<br> moles of<br> Lithium<br> carbonate?
frutty [35]

Answer:

244.76

Explanation:

The weight of grams by 1.82 moles of lithium carbonate would be: 134.481438 So we need to use this equation to find mass by grams m × g = ms Where m is for moles, g for grams, and ms for mass. So now we need use this equation: 1.82 × 134.481438 = ? 1.82 × 134.481438 = 244.75621716 244.75621716, rounded-up (to the nearest-tenths place) is 244.76. So now you have it! The mass of 1.82 moles of lithium carbonate is 244.76!

Hi can someone help me quickly please its for chemistry
lara [203]

Answer:

Explanation:

The atom X has 1 1 protons (atomic number) and thus would have 11 electrons. This means the atom X would have 1 valence electron in it's outermost shell. While the atom Y has 17 protons (atomic number) and thus would have 17 electrons. This means the atom Y would have 7 electrons in it's outermost shell.

The type of bond this atoms (X and Y) would form is an Ionic (or electrovalent) bond. <u>This bond/combination involves the transfer of electron(s) and a molecule is not formed</u> as seen in the image below.
