Answer:Mass is measured on a triple beam balance units = GRAMS.
Volume is measured in two ways.
Regular Object = Length X Width X Height units = cm3
Irregular Objects units = mL
Pour about 50 mL of water into a graduated cylinder. Measure and record the exact amount.
Add the object. Measure and record the new water level.
SUBTRACT the original water amount from the new water level to find the volume of the object.
= MASS (g)
VOLUME (cm3
)
Example One:
A mineral has a mass of 100g and a volume of 10 mL. What is its density?
= mass = 100g = 10 g/mL
Volume 10 mL
Example Two:
A mineral has a mass of 25 g and a volume of 5 cm3
. What is its density?
= mass = 25g = 5 g/cm3
Volume 5 cm3
**Mass ÷ Volume to find the numerical answer. Bring over BOTH units**
Explanation:
The correct answer to the question is B) 5,700 years.
EXPLANATION:
Before going to answer this question, first we have to understand half life period of a radio active substance.
The half life period ![[\ T_{1/2}\ ]](https://tex.z-dn.net/?f=%5B%5C%20T_%7B1%2F2%7D%5C%20%5D)
of a radio active substance is defined as the time in which half of the radio active specimen has undergone decay.
As per the question, the initial concentration of the radioactive carbon-14 is given as 10,000.
Hence, initial concentration 
.
After 5,700 years, the remaining radio active specimen is 5000. It means that half of the radio active specimen has undergone decay in 5,700 years.
Hence, half life period of the radio active carbon-14 specimen is 5,700 years.
If an element has a atomic number of 8 and a mass number of 18, then the number of protons us also 8
