C) 56.31 gm/mol D) 59.14 gm/mol

Explanation:

To get the mass of a mole of NaCl, we need to add the molar atomic weights of the individual elements i.e, Na and Cl

Atomic weights of Na = 22.99 gm/mol  Cl = 35.45 gm/mol

 

Now, mass of a mole of NaCl = 22.99 + 35.45 = 58.44 gm/mol.

Fever in the season of dengue is sending Calcuttans scurrying to hospitals for admission, triggering a shortage of beds that has forced some private health care institutes to even postpone planned surgeries. Apollo Gleneagles Hospitals on the Bypass had 504 patients in its care as on Thursday of whom 70 had been admitted with fever. Belle Vue Clinic had 180 patients, 32 of them with dengue. Calcutta Medical Research Institute had 350 patients 60 of them with fever.

The number of people admitted for treatment of fever caused by dengue or any undiagnosed illness has been rising every day across hospitals for more than a fortnight.

"There has been heavy pressure on all private hospitals for admission of dengue and cases of unknown fever since the beginning of August. Now it is a surge," said Pradip Tondon, President of the Association of Hospitals of Eastern India.

In July, four to five patients were getting admitted with fever on an average in every hospital. The number has since ballooned with the Calcutta Municipal Corporation apparently in denial about the extent of the dengue outbreak and the Government focused on playing down the threat.

Such has been the rush of patients with fever that some hospitals are calling up people to postpone admissions planned in advance, mostly for surgeries. "We have told many people to come only when we call them to confirm availability of beds," said an official at Belle Vue.
