We will need to know Avogadro's number and the molar mass of sucrose for this problem to do dimensional analysis.
- Avogadro's number: 6.022 × 10²³ molecules
- Molar mass of sucrose: 342.2965 g/mol
250g × × = 4.398 molecules
There are <em>4.398 sucrose molecules </em>in 250 grams of sucrose.

a double replacement reaction, because the hydrogen of the acid change places with the potassium of the base, forming salt and water...
Answer:
a
Explanation:
because titration by definition, is used to determine the concentration of one reactant in an aqueous solution, it requires a burette to accurately measure the volume of a solution and endpoints in acid-base titration can be determined by a colour indicator or a pH meter
Answer:Al3+ indicates an ion of aluminum having a charge of + 3. I.e., since an aluminum atom normally has 13 protons and 13 electrons, this ion has 10 electrons (-10 charge) and 13 protons (+ 13 charge) giving it a charge of + 3 (-10 + 13 = +3).
Explanation:
Answer:
80.1 = 6158.46
Multiply 9.119.11 by 1010.
91.1−11=6.02⋅102391.1-11=6.02⋅1023
Subtract 1111 from 91.191.1.
80.1=6.02⋅102380.1=6.02⋅1023
Multiply 6.026.02 by 10231023.
80.1=6158.4
