2 answers:

7 0

Ethical concerns affect scientific research when scientists or groups of scientists let their personal bias or political persuasions affect the research being conducted. Scientific ethics involve doing experimentation and analysis of data without bias no matter what the conclusions point to.

Answer:

The density of the metal sample is 2.70 $\frac{grams}{mL}$

Explanation:

Density is a magnitude that allows you to measure the amount of mass in a given volume of a substance. Then, the expression for the calculation of density is the ratio between the mass of a body and the volume it occupies:

$d=\frac{m}{V}$

Density, according to the International System of Units, is usually expressed in kilograms per cubic meter (kg / m3) or gram per cubic centimeter (g / cm3). Although it can also be expressed in any other unit of mass by volume.

So, for the calculation of density you know that:

mass of the sample= 10 grams
volume of the sample = volume on the cylinder after immersion - volume on the cylinder before immersion= 38.7 mL - 35.0 ml = 3.7 mL

Then:

$d=\frac{10 grams}{3.7 mL}$

d=2.70 $\frac{grams}{mL}$

The density of the metal sample is 2.70 $\frac{grams}{mL}$

A gas cylinder contains 15 moles of 02. How many molecules of oxygen are in the cylinder

Travka [436]

The answer is 9.03 × 10²⁴ molecules of oxygen!

Step 1 6.02 × 10²³ molecules : 1 mol = x : 15 mol
Step 2 x = 6.02 × 10²³ molecules * 15 mol * 1 mol
Step 3  x = 90.3 × 10²³ molecules
Step 4 x = 9.03 × 10 × 10²³ molecules
Step 5 x = 9.03 × 10²³⁺¹ molecules
Step 6 { x = 9.03 × 10²⁴ molecules }
