Write the given numbers in standard notation, maintaining the same number of significant figures.
svetlana [45]

Answer:

0.0761.

0.0059.

Explanation:

Hello!

In this case, since the writing of numbers in standard notation given the scientific notation requires adding zeros to the left of the first nonzero digit, for the first number, we need to add two zeros as seven is the third digit position:

0.0761.

Next, we need to add three zeros as 5 would be the fourth digit:

0.0059.

Best regards!

How many atoms of oxygen are present in 7.51 grams of<br> glycine with formula C₂H5O2N?
Blizzard [7]

1.205 × 10²³ atoms of oxygen will be present in 7.51 grams of glycine with formula C₂H5O2N. Details about number of atoms can be found below.

How to calculate number of atoms?

The number of atoms of a substance can be calculated by multiplying the number of moles of the substance by Avogadro's number.

However, the number of moles of oxygen in glycine can be calculated using the following expression:

Molar mass of C₂H5O2N = 75.07g/mol

Mass of oxygen in glycine = 32g/mol

Hence; 32/75.07 × 7.51 = 3.2grams of oxygen in glycine

Moles of oxygen = 3.2g ÷ 16g/mol = 0.2moles

Number of atoms of oxygen = 0.2 × 6.02 × 10²³ = 1.205 × 10²³ atoms

Therefore, 1.205 × 10²³ atoms of oxygen will be present in 7.51 grams of glycine with formula C₂H5O2N.

Consider solutions A and B
lisabon 2012 [21]

Answer: Option c. Solution A has a lower boiling point than solution B

Explanation:

For solution A, i = 1 means the solution is a non-electrolyte. This clearly indicates that solution A contains covalently bonded compound. Covalently bonded compounds have lower boiling when compared to those of the ionic.

For solution B, i = 2 means the compound is an electrolyte and it forms two ions. From this result, it is very clear that the compound in solution A is an ionic compound. Ionic compounds have higher boiling points than covalent compounds

Therefore, solution A will have a lower boiling point than solution B
