Apply scientific knowledge and understanding to determine how many grams of carbon dioxide are produced from the combustion of 2
lidiya [134]

Answer:

749 grams CO₂

Explanation:

To find the amount of carbon dioxide produced, you need to (1) convert grams C₃H₈ to moles C₃H₈ (via molar mass from periodic table), then (2) convert moles C₃H₈ to moles CO₂ (via mole-to-mole ratio via reaction coefficients), and then (3) convert moles CO₂ to grams CO₂ (via molar mass from periodic table). It is important to arrange the ratios/conversions in a way that allows for the cancellation of units. The desired unit should be in the numerator. The final answer should have 3 significant figures because the given value (250. grams) has 3 sig figs.

Molar Mass (C₃H₈): 3(12.01 g/mol) + 8(1.008 g/mol)

Molar Mass (C₃H₈): 44.094 g/mol

1 C₃H₈ + 5 O₂ ---> 3 CO₂ + 4 H₂O

Molar Mass (CO₂): 12.01 g/mol + 2(16.00 g/mol)

Molar Mass (CO₂): 44.01 g/mol

250. g C₃H₈         1 mole C₃H₈           3 moles CO₂              44.01 g
------------------  x  ----------------------  x  ----------------------  x  --------------------  =
                               44.094 g              1 mole C₃H₈            1 mole CO₂

= 749 grams CO₂

Significant figures are a measure of __________. an precise and accurate answer. the true value of a measurement. accuracy. prec
34kurt

Answer:

Significant figures are a measure of <u><em>precision</em></u>.

Explanation:

The significant figures of a number are those that have a real meaning and, therefore, provide some information. Therefore, the set of digits that are known with certainty in a measure are called significant figures and are the digits of a number considered non-null.

Any experimental measurement is inaccurate and must be expressed with its significant figures.

In this way, significant figures express the precision of a measuring tool.

How many carbon atoms are there in the empirical formula corresponding to C10H22O2?
podryga [215]

Empirical formula of the compound contains 5 carbon atoms.

Explanation:

We have the molecular formula of the compound C₁₀H₂₂O₂.

To find the empirical formula we divide each number of atoms by the lowest number which is 2:

for carbon (C) 10 / 2 = 5

for hydrogen (H) 22 / 2 = 11

for oxygen (O) 2 / 2 = 1

The empirical formula is C₅H₁₁O and contains 5 carbon atoms.
