Answer:
325mg of Aspririn
Explanation:
First you should note the information that the problem gives you:
- The bottle of Aspirin has 5gr (grains)
- 1gr(grain) = 65mg (miligrams)
Also, the problem is asking about how many aspirin are in 5 gr (grains), so you should use a conversion factor, as follows:
-First you should put the quantity you need to convert:
-Then you write the denominator of the conversion factor that must have the same units that you want to convert, in this case gr:
-Then you write the numerator with the units that you want to obtain and the numerical equivalence between the units, in this case:
-Finally you multiply numerators and divide by denominators:
2721.55422g
Explanation:
First, step is to find out how much is 1pound in grams.
So,
1 POUND x (1 KG/2.204 POUND) x (1000G/1 KG) which is equal to 453.59g
Here, we got that 1 pound is equal to 453.59g.
In the question, it is given that the weight of the baby is 6 pound.
To convert 6 pounds into grams, we need to multiply 6 pounds with 453.59 g,
6pounds x 453.59g = 2721.55422 g
Hence, the weight of the 6-pound baby in grams will be 2721.55422 grams.
The weakest attractive force is london - dispersion forces
Explanation
- London- dispersion forces is aweak van der waal forces.
- London dispersion forces is the weakest intermolecular forces.
- Is a temporary attractive force when electron in two force that result when electron in two adjacent atoms occupy position that make the atoms form a temporary dipoles.
If rotation turns towards the sun then it is considered day. When the Earth rotates away from the sun, it is considered night.
Answer:
40.1 g
Explanation:
The <em>balanced equation</em> is:
First we <u>convert 86.5 g of calcium chlorate into moles</u>, using its<em> molar mass</em>:
- 86.5 g Ca(ClO₃)₂ ÷ 206.98 g/mol = 0.418 mol Ca(ClO₃)₂
Then we <u>convert Ca(ClO₃)₂ moles into O₂ moles</u>, using <em>the stoichiometric coefficients of the balanced reaction</em>:
- 0.418 mol Ca(ClO₃)₂ *
= 1.254 mol O₂
Finally we <u>convert O₂ moles into grams</u>:
- 1.25 mol O₂ * 32 g/mol = 40.1 g O₂
