The gravitational force between a mass and the Earth is the object's weight. Mass is considered a measure of an object's inertia, and its weight is the force exerted on the object in a gravitational field. On the surface of the Earth, the two forces are related by the acceleration due to gravity: Fg = mg.
The atomic mass is useful in chemistry when it is paired with the mole concept: the atomic mass of an element, measured in amu, is the same as the mass in grams of one mole of an element. since the atomic mass of iron is 55.847 amu, one mole of iron atoms would weigh 55.847 grams.
1.18 to microliters is 0.0118 i am sure, so use a table and note in 4 boxes, the first one write liters, then the next write deciliters, then milliliters in the next then microliters, last nanoliters, you want to find the answer of how many micro liters there are in liters so 1.18 just move the decimal to the right each time you go right in the liters boxes, also add two zeros like this 0.0118, boom.
Answer:
7
Explanation:
The pH of water is 7.
pH is the convenient scale for expressing the level of acidity or alkalinity of aqueous solutions.
An acidic solution has a pH value less than 7.
As pH decreases, the acidity of solutions increases.
Neutral solutions have a pH of 7.
An alkaline solutions has a pH greater than 7 and the level of alkalinity increases as the pH increases.
Water has a pH of 7 because the concentration of hydrogen and hydroxyl ion is equal.
Anything greater that 7 is a base....so 13 would be a very strong base for example a drain cleaner. Hopefully this is what you are looking for.
