Answer: 207.2
Explanation:
In imprecise terms, one AMU is the average of the proton rest mass and the neutron rest mass. This is approximately 1.67377 x 10 -27 kilogram (kg), or 1.67377 x 10 -24 gram (g). The mass of an atom in AMU is roughly equal to the sum of the number of protons and neutrons in the nucleus.
Which of these is a physical property?A. Malleable
To determine the pressure in units of kPa, we need to use a conversion factor to convert the units from mmHg to kPa. A conversion factor is a value that would relate two different units and is multiplied or divide to the original measurement depending on what is units is asked. From literature, 1 atm is equal to 760 mmHg and it is also equal to 101.325 kPa. We use these factors to convert the given value. We do as follows:
2150 mmHg ( 1 atm / 760 mmHg ) ( 101.325 kPa / 1 atm ) = 286.643 kPa
Therefore, the closest value from the choices is the second one which has the value of 287, this would be answer.
Answer:
<em>D</em><em>.</em><em>They have properties similar to those of their component elements.</em><em> </em>
Explanation:
When elements are joined, the atoms lose their individual properties and have different properties from the elements they are made of .
Answer:
mass/volume
Explanation:
The slope is rise over run, or y over x. The mass is y on this graph, and the volume is x on this graph. The slope represents mass over volume.
