Answer:
Explanation:
See attached table.
Note that:
1 mole = 6.02x10^23
Molar mass is grams/mole. For the elements, the atomic mass is the same number as molar mass, just expressed as grams/mole.
Calculate the H positive from the pH equation: pH equals -log (H positive). This would be 10 to the -6.49. Let's call the acid HA. To calculate Ka in this equation, Ka equals H positive times A- over HA. HA is going to be the 0 0121. So, Ka=(10^-6.49)^2/0.0121. This equals 1.05*10^-13/0.0121. Ka then equals 8.65*10^-12.
Answer:
Volume is often measured numerically using the International System of Units (SI unit), the cubic meter. for example volume of a cube is measured using a cubic centimeter (cm3), the metric system includes the liter (L) as a unit of volume, where one liter is the volume of a 10-centimeter cube.
