Finding an object's mass is usually easy, while identifying its volume can be tricky. Simple-shaped objects, such ascubes, bricks, or spheres, are usual topics for density homework problems. You can usea formulato find the volume of one of these simple shapes. For irregular shapes, measuring...
Calculate the density in grams per liter of the following gases at STP: (a) NO (b) NO2 (c) O2 How can you determine how many moles were produced from a given equation in chemistry? How to convert mL to gallons with a formula ...
You want to find the density of an irregularly shaped "Object X." You measure the mass of Object X using an analytical balance, you find the mass to be 43.485 g. You measure 49.8 mL of water in a graduated cylinder, add in Object X, and see the...
The key to using jumping rope to increase your cadence is to keep your jumps low and fast. Don’t think of the leisurely jumping rope on elementary school playgrounds; this is an athletic style of jumping rope that trains boxers, soccer players, and other athletes. Jumping rope can not onl...
to find out how many g of helium you need to put into the balloon. After you get that number . .. you then multiply that number by Helium's molar mass to get the amount of moles of Helium you need . . . then take the amount of Helium and multiply by STP (22.4L) to find the...
The conversion from fumaric acid to maleic acid can be done by hydrolytic conversion. The fumarase may catalyze this reaction with the help of a liquid membrane. Answer and Explanation:1 Usually, fumaric and malic acids are the geometrical isomers, which means the molecular f...

Finally, knowledge or assumption of the adsor- bate density ρo allows for the determination of the dry mass, mo. The modeling of the SE data requires SE reference measurements that provide information on the optical properties of the substrate, Approaches to analyze the QCM-D data ambient ...
Answer and Explanation: To find the amount of HCl formed, we have to first define the ratio of the reaction. So we have to calculate the formula mass of both reagent and...
How do you convert the pressure 0.250 Atm to kPa? How do I find the change in temperature? The pressure of a gas is 25 atm at 475 K. Find its temperature at standard pressure. (STP = 1 atm.) If both temperature and volume of an ideal gas are halved, how does the pressur...
