An alloy is made up of two kinds of metals. This alloy is uniform in appearance. How would this material be classified?

To calculate the empirical mass of a compound from the mass percentage of each element, the value of the<u> molar mass </u>of each element is used, which in this case corresponds to:

$MM_C= 12g/mol\\MM_H=1g/mol\\MM_O=16g/mol$

From this, we consider that the compound has 100 grams, so the number of moles of each element will be equal to:

$C = \frac{40.92}{12} = 3.41 \\H = \frac{4.58}{1}=4.58\\ O =\frac{54.50}{16}=3.41$

Now, divide all the values found by the <u>smallest value</u>, to find the amount present in each element:

$C = \frac{3.41}{3.41} = 1\\ H = \frac{4.58}{3.41} = 1.34\\O = \frac{3.41}{3.41} = 1$

As you can see, the value of moles of hydrogen resulted in a decimal number, so it is necessary to multiply all values by a number in common until the three meet as integers:

$C = 1 \times 6 = 6\\H = 1.34 \times 6 = 8\\O = 6 \times 6 = 6$

So, the empirical formula of ascorbic acid is C6H8O6.

What mass in kilograms does 4.41 moles of copper have?

aalyn [17]

Answer:

0.280 kg

Explanation:

m= n × MM

where

m is mass in grams

n is moles &

MM is molecular mass

The molecular mass of copper can be found on the periodic table and is 63.546.

We now have all the required information to perform the calculation

m= 4.41 × 63.546

m= 280.23786

m= 280 g

In order to convert this value to kilograms, divide by 1000

280/ 1000

= 0.280 kg

Concepts and reason

This problem is based on the concept of Nuclear magnetic resonance which involves the absorption of radiations in the radio frequency region. This spectroscopy is generally used for the determination of the type and number of protons present in a molecule.

Fundamentals

A spinning charge creates a magnetic field and therefore behaves as a tiny magnet . The spinning nuclei generate a magnetic field on exposure to an external magnetic field . If an external magnetic field is applied , spinning nuclei can get oriented in two ways:

The magnetic field due to nuclei is in the same direction as the external field. In this case, the nuclei are said to be in a low energy spin state.

The magnetic field due to nuclei is in the opposite direction as the external magnetic field. In this case, the nuclei are said to be in high -energy spin state.
