Read the rest >Here we looked at all the ways we could answer the following question: "What times what equals 51?" To do this, we calculated all possible solutions to this problem: what x what = 51 Note that "what" and "what" in the above problem could be the same number or different numbers. Below is a list of all the different ways that what times what ...
Read the rest >Ten raised to the sixth power is equal to one million or 1,000,000, which is a one followed by six zeros. Raising a number to a power of six is the same as multiplying the number by itself six times. Working with powers of 10 can be easily visualized by adding a zero each time the power increases by one. Ten to the second power is 10 times 10, or 100.

Finding equivalent fractions can be ease if you use this rule: Equivalent fractions definition: two fractions (a/b and c/d) are equivalent only if the product (multiplication) of the numerator (a) of the first fraction and the denominator (d) of the other fraction is equal to the product of the denominator (b) of the ...
Read the rest >For dilute solutions, one part per million equals one mg/L. In most cases, the two are considered equal. To convert from molarity to ppm, first determine the molar mass of a substance. For instance, chloride has a molar mass of 35.5. A solution with 1 M concentration would …
Read the rest >Mar 26, 2017 · HC2H3O2 is a weak acid (its not one of the strong acids you memorize, and also you can see it has a low Ka). NaC2H3O2 is its conjugate base( they differ in only one hydrogen, and base always has one H less than an acid). You also have equal amount of both, which makes this a perfect buffer.

Read the rest >It makes it easy to use big and small values. When the number is 10 or greater, the decimal point has to move to the left, and the power of 10 is positive. When the number is smaller than 1, the decimal point has to move to the right, so the power of 10 is negative ...
Read the rest >There are 1.0E-6 meter in a micrometer. 1 Micrometer is equal to 1.0E-6 Meter. 1 um = 1.0E-6 m. A micrometer, or micron, is a unit of length sometimes used in SI as a 1×10−6 of a meter. This is a quite specific measurement unit used in science (i.e. for measuring various types of wavelength, etc.) or in industrial technology.
