How many molecules of sugar are there in 1 can of soda?
Korvikt [17]

Answer:

5.8\cdot 10^{22}

Explanation:

Since no information was provided about the can of soda, let's take an example of 1 can of 12 fl oz (368 g) Coca-Cola.

The nutrition facts state that it contains 33 g of sugar. In order to calculate the number of molecules, we firstly need to know the molecular formula of sugar. Sugar can be represented by C_{12}H_{22}O_{11}.

Our first step is to find the molar mass of sugar:

M_{C_{12}H_{22}O_{11}} = 342.3 g/mol

Secondly, dividing mass of sugar, m = 33 g, by the molar mass will yield the number of moles of sugar:

n_{C_{12}H_{22}O_{11}}=\frac{m}{M}

Finally, multiplying moles by the Avogadro's constant will yield the number of molecules:

N_{C_{12}H_{22}O_{11}}=n_{C_{12}H_{22}O_{11}}\cdot N_A =\frac{m}{M} \cdot N_A = \frac{33 g}{342.3 g/mol} \cdot 6.022 \cdot 10^{23} mol^{-1} = 5.8\cdot 10^{22}

Arrange the following elements in order of increasing from smallest to largest atomic size K,O, Cs, Se explain why the reason wh
lyudmila [28]

Answer:

smallest is O then Se then K then Cs.

Explanation:

These trends exist. elements tend to get smaller as it completes it's shell since there is more attraction when it is complete. plus the further down the periodic table you go the bigger it is. there are more electrons which repulse each other and make it bigger.
