The molecular formula of morphine, a pain-killing narcotic, is c17h19no3. what is the molar mass? what is the mass of 6.02 x 102
kati45 [8]
<span>Molar mass is the mass of one mole of a substance, it can be a chemical element or a compound. It is a characteristic of each pure substance. We calculate it by adding up all of the masses of the atoms involved in the compound. We calculate as follows:
                   atomic mass         total mass
C     17        12.01 g/mol          204.17 g/mol
H     19          1.01 g/mol           19.19 g/mol
N      1         14.00 g/mol            14.00 g/mol
O      3         16.00 g/mol            48.00 g/mol
------------------------------------------------------------
Molar mass                           = 285.36 g/mol

</span><span>What is the mass of 6.02 x 10^24 molecules of morphine?

</span>6.02 x 10^24 molecules ( 1 mol / 6.02x10^23 molecules) ( 285.36 g/mol) = 2853.6 g morphine

marusya05 [52]
<span>The weight of the precipitate was 17.550g - 17.410g = 0.140g. From a 10ml sample, this means the concentration was 0.140g / 10ml, which is equal to 0.014g/ml.</span>

A competitive inhibitor of an enzyme-catalyzed reaction - cannot bind to the active site. - always interferes with product relea
Brut [27]

Answer:

is usually structurally similar to the substrate.

Explanation:

Competitive inhibitors resemble normal substrate and binds to enzyme at the active site usually and prevents substrate from binding.

Active sites are main location for the substrate-enzyme binding. These sites involve weak as well as reversible bonds between the substrate and the enzyme. These inhibitors bind to the active sites and form weak and  reversible bonds. Competitive inhibitors can be dissociated from active site by increasing concentration of the substrates. Substrates has to compete for active site and displace the bound competitive inhibitors.

<u>Hence, correct option is - is usually structurally similar to the substrate.</u>
