How law of constant proportion is applied in experiment empirical formula of magnesium oxide?
The law of constant proportion states that a chemical compound always contains its constituent elements in fixed ratio by mass. In the experiment to determine the empirical formula of magnesium oxide, magnesium is burned in oxygen, resulting in magnesium oxide. By measuring the mass of magnesium and the mass of oxygen reacted, the ratio of these two elements can be calculated. This ratio reflects the law of constant proportion, allowing the empirical formula of magnesium oxide to be determined, typically represented as MgO.
How one has more molecules 9g of water or9g of sugar?
Perhaps you mean: Does sugar have more atoms than water?In a certain fixed mass of sugar/water, there will be more molecules of water than of sugar since the molecular mass of sugar is higher than that of water. We follow the rule of Mass = Number of moles of a substance * Molecular mass of the substance.We rearrange this to form Number of moles = Mass / Molecular massTherefore, since the molecular mass of sugar is higher, the number of moles of sugar in a fixed mass of sugar is lower. The number of moles of sugar is directly proportional to the number of molecules of sugar, since we follow Avogadro's Law:1 mole = 6 * 10^23 molecules (constant value)However, if you meant to ask if sugar had more atoms than water, the answer is yes, it does. Sugar (presumably glucose) has the chemical formula of C6H12O6 and thus has 24 C, H and O atoms altogether. Water, with the formula H2O, has 3 atoms of H and O altogether.I hope this was helpful! :)
The elements in a are always combined in the same proportion by mass?
From many years this affirmation is not considered valid.
When sugar is dissolve in water and the water is evaporated off the mass of the sugar does what?
When sugar is dissolved in water and the water is evaporated off, the sugar will crystallize and recrystallize, resulting in the formation of sugar crystals. The mass of the sugar will remain the same as the initial amount of sugar added to the water.
The atomic mass of N is 14 you and that of Ca is 40 you The proportion of N by mass in the compound Ca3N2 is?
To find the proportion of N in Ca3N2, we calculate the total atomic mass of N in the compound which is 2 * 14 = 28 (since there are 2 nitrogen atoms in Ca3N2). The total atomic mass of Ca3N2 is 3 * 40 + 2 * 14 = 136. Therefore, the proportion of N in Ca3N2 by mass is 28/136 = 0.206 (or 20.6%).
What is a fixed proportion in chemistry?
A fixed proportion in chemistry refers to the specific ratio in which elements combine to form compounds. This means that the elements in a compound are always present in the same proportion by mass. For example, water is always composed of hydrogen and oxygen in a 2:1 ratio by mass.
What does having a fixed composition mean?
Having a fixed composition means that a substance always contains the same elements in the same proportion by mass. This characteristic is a defining feature of pure substances like elements and compounds.

Does fixed mass of gas have fixed volume?
No.
Does a liquid have a fixed mass under conditions?
The mass of a given volume of a liquid is fixed.

How many grams sugar in 1 teaspoon?
a very small teaspoon is only one gram of sugar and a very large teaspoon ,might be ounces of sugar but there is no fixed density or volume or even mass
When you divide mass by volume you get a proportion called?
Density

Is the total mass of the universe increasing decreasing or fixed?

A sugar solution of 35.8g sugar and 125.35g of water. what is the percent by mass of the sugar and the percent by mass of the water in the solution?
add 35.8g sugar to 125.35g of water this = 100% of the solution. then divide 35.8g of sugar by the whole solution and multiply by 100 to get the percentage (35.8)/ (125.35 + 35.8)= .222 * 100= 22.2% sugar is 22.2% of the solution. Do the same for the water switch 35.8 by 125.35
